Book review: ‘The Book of Two Ways’ | Features | –

The Book of Two Ways, by Jodi Picoult (Ballantine)

Jodi Picoults The Book of Two Ways follows Dawn Edelstein, a death doula with a physicist husband and a teenage daughter. Dawns job is to help terminally ill patients and their loved ones transition from life to death.

But before she was a death doula, she was a graduate student living in Egypt, studying archeology and in love with a fellow graduate student named Wyatt.

When Dawn is in a plane crash, she finds not the life she lives flashing before her eyes, but rather the life she once had with Wyatt 15 years earlier.

After miraculously surviving the crash, Dawn must consider whether to return home to her family or travel to Egypt, find Wyatt and discover the life that could have been and maybe could be.

What unfolds are two side-by-side stories of where each of Dawns choices lead her.

The Book of Two Ways is a thrilling adventure, but the many timelines woven through the novel can be a bit difficult to follow. With Picoults stories, there is always something new to learn, and The Book of Two Ways is no exception. The characters interests in ancient Egypt, quantum physics, death, and more bring a certain dynamism to the story, but at times, can also get a bit dense.

Nevertheless, Picoult has certainly crafted a fun and interesting read, one that will lead readers to both learn a lot and also ask themselves key questions about how to create happy lives for themselves during the short time we have on earth.

Book Review: Six Impossible Things, By John Gribbbin – Forbes

Cover of John Gribbin's "Six Impossible Things" from MIT Press

John Gribbin is a fairly significant figure in general-audience physics writing, with his In Search of Schrdingers Cat widely regarded as a classic of the genre. So when a small new book by him showed up in my mailbox at work, I flagged it as something Id need to read. Unfortunately, it arrived at a time when I was busy with work, and then of course this was this whole global pandemic situation, and as a result, its taken me quite a while to get around to it...

Six Impossible Things: The Mystery of the Quantum World is a book about the interpretation of quantum mechanics (a subject that, I should note up front, I am more than a little tired of). Riffing off the obvious Alice in Wonderland quote, this presents two Fits describing problematic elements of quantum physics (particle-wave duality and entanglement), whose true meaning needs to be interpreted. These are followed by six Solaces, brief summaries of particular interpretations (Copenhagen, de Broglie-Bohm pilot waves, Many-Worlds, decoherence, the ensemble interpretation, and the retrocausal Transactional Interpretation) . Gribbins stated goal is to present an agnostic overview for each, offering both pros and cons.

This is a very short book none of the Solaces runs more than a dozen pages and as a consequence, the discussions are very abbreviated. Some of the discussions are very poorly served by this enforced brevity. Theres one particular bit in the many-worlds chapter where he discussed quantum computing thats so compressed as to be nearly incomprehensible. I know a fair bit about quantum computers, and it still took me an inordinately long time to figure out what one particular passage was getting at. Its not wrong, but its very unclear, and took me a while to convince myself that it was just a lossy compression of something mostly correct.

I think that gets at the central issue I had with this book, which is that Im really not sure who its for. The presentations of the individual interpretations arent detailed enough to really work for someone who doesnt already have some idea of the issues involved, but they dont go into enough depth to reveal anything novel to people who do know something of the underlying physics. Its likely to leave experts underwhelmed and newbies underinformed.

But then, as noted above, I find myself somewhat dyspeptic regarding the whole topic of quantum interpretations these days, so take that with the appropriate seasoning. One of the more appealing aspects of the book, oddly, was that his striving for agnosticism made most of the presentations feel skewed toward the negative, which sort of suited my mood...

And, to be sure, there is definitely an audience for books that strike me as short on information but long on literary virtues. In that sense, its somewhat akin to Carlo Rovellis Seven Brief Lessons on Physics (reviewed here), or exercises like Roberto Trottas The Edge of the Sky (reviewed a long time ago) that use highly restricted vocabulary.

And despite the self-imposed limitations on the depth of the content, Gribbin brings plenty of writerly skill to the table. In fact, given the limitations of the very short form, it would almost make more sense to praise its impressive concision than to lament its lack of depth. Gribbin writes engagingly and approachably about deep and subtle topics, and theres more right than wrong in his descriptions. It may also serve to point readers in the direction of other, more in-depth explorations (Id recommend Anil Ananthaswamys Through Two Doors At Once, which I reviewed here).

So, at the end of the day, this is one of those Reviews of Limited Utility that mostly boils down to This book wasnt really for me. I remain somewhat uncertain as to who it really is for, but if you enjoyed the Rovelli and Trotta books mentioned above, its probably worth a look. If nothing else, it wont take long to read...

Honeywells Tony Uttley And The Quest For Quantum – Forbes

Tony Uttley, the President of Honeywell Quantum Solutions (

If you are not a scientist or a techie, and perhaps even if you are, the word quantum might sound like something out of Star Trek. Its futuristic, for sure, but it is not fiction. Quantum computers, and the genuinely revolutionary computational power it promises, may not be too far off at all. At the vanguard of quantum computing is a name you might not expectHoneywell. While the company used to be known for its smart home products, such as thermostats or smoke alarms, the multinational conglomerate has more of its fingers in a lot more technology pies. Honeywell plays in four main areas: aerospace, performance materials and technologies, building technologies, and safety and productivity solutions. The industrial side of the business, through Honeywell Connected Enterprise, is creating momentum in the EPM (Enterprise Performance Management) category, with its industry-leading IoT platform, Honeywell Forge.

And, as we will go into today, one of the most radical, potentially world-changing technologies currently in developmentquantum computing. Behind Honeywells push in advancing quantum is a man named Tony Uttley, the President of Honeywells Quantum Solutions unit. Moor Insights & Strategy has been following Honeywells efforts in this area closely, and I jumped at the recent opportunity to interview Uttley on his units efforts and progress. Lets dive into Honeywell and Uttleys quantum journey.

What is quantum computing?

Before we get started, we should define what were talking about. Highly simplified, instead of using traditional computer bits (which operate on the binary of either on or off or 1 or 0), quantum computers utilize qubits, which possess the unique ability to be in both the 1 and 0 states simultaneously thanks to a property of quantum physics called superposition. Additionally, these computers can perform computations simultaneously, instead of sequentially (like traditional computing). It can do this due to entanglement, a quality of qubits that allows them to be joined together in a way that will enable each qubit to hold the information about all the others in the grouping (called a register in quantum jargon).

These qualities, combined, promise to blow the current most advanced supercomputers out of the water in terms of compute power and speed, with the potential to unlock technological advancements beyond what we can even fathom at this point.

While discussing the potential, Uttley shared a useful analogy: when classical computers were being developed, at the time, people thought there would only need to be a handful of them in the world. Sixty years later, and most people carry around their tiny computers in their pockets wherever they go. Computers have progressed and become more ubiquitous and profitable than anyone could have possibly imagined in the early days. And thats where we are now with quantum computingthe early days.

Along came Tony

But lets rewind a little bit because its worth knowing how the man at the helm of Honeywells Quantum Solutions division ended up there. Uttley got his career start at NASAs Johnson Space Center, as the operations manager at NASAs Neutral Buoyancy Laboratory excited to apply his skills to the space program. He spent a decade at NASA, but at some point along the way realized that he was better at convincing really, really smart people to do things than actually doing them himself. This led to him transitioning to the world of strategy consulting, where he ended up working for the Boston Consulting Group for seven years, helping clients figure out how to achieve their business goals.

When he arrived at Honeywell, about a decade ago, he initially led global strategy and marketing for Honeywells largest division at the time, Automation & Control Solutions, an $18B portfolio of residential, commercial, and industrial controls. Following that role, Uttley led the companys residential business within the Americas Region. There he was responsible for driving the upgrade of Honeywells legacy thermostats (the bread and butter for the company for nearly a century) into connected, app-based smart thermostatsa foray into the new world of the smart home that Honeywell had never attempted before. It was a big undertaking, but, as a guy with a penchant for strategizing big ideas into fruition, Uttley was the man for the job.

Honeywells quantum leap

Honeywells quantum exploration began with two Ph.D. researchers coming forward with an intriguing proposition: Honeywells broad scope of technology was already uniquely suited to take on building a quantum computer. The company was already a leading manufacturer of hardware and software control systems, advanced electronics and optics and photonics (lasers, fiber optics, modulators, cryogenics, and ultra-high vacuum environments), all of which you need to build a quantum computer. Despite thinking it was the coolest thing ever, Uttley admitted he was initially skeptical due to it still being the very early days of quantum computing at the time.

After discussing it with higher-ups, however, an agreement was reached that pursuing the ambitious goal of quantum computing was, in fact, in line with Honeywells strategic imperatives to be a technology leader. Additionally, since many of the underlying technologies were already in development at Honeywell, investing in them and advancing them would benefit the rest of Honeywells business simultaneously. Lastly, Honeywell is one of the worlds leading controls companies, and quantum computing is, at its heart, a controls problem. Honeywell made critical investments to pursue the idea further. The questions that needed to be answered, to push the project forward were:

a)Can Honeywell build something that is genuinely a differentiated Quantum computer?

b)How can Honeywell leverage quantum technology, at this early stage, to customers benefitwill anyone pay to use it?

After the company felt like it had developed a differentiated capability with real potential, it formed a full team around the project, employing atomic, molecular, and optical physicists and other scientists, technicians, and engineers with specializations in trapped-ion quantum computing.

Challenges ahead demand trust

Uttley stressed the importance of building trust with the ecosystem around Honeywells quantum computer. While currently, the results of algorithms run on quantum can be tested and validated against those that run on classical computers, once the company pushes past the barrier of whats possible with classical computing, there will be nothing to cross-reference and validate results with. Honeywell will have to trust in its execution and be able to transfer that trust effectively to others to convince them to step into what Uttley called the virtual unknown. I suspect his knack for selling people on big ideas might come in handy there.

He went on to say that the scarcest resource right now, as quantum moves forward, is the lack of people. As he puts it, all the people who know how to do quantum computing have been gobbled up by companies such as Honeywell, startups, national labs, or academia. The next capacity constraint, according to Uttley, lies in the quantum computing systems themselves. Honeywell is only building a few systems because it knows the second generation will be coming down right behind it. Given the nature of quantum computing, it will potentially be 100,000 times better than the first. As he tells it, this could severely cut down the time to access the system itself. Because of this, Honeywell has been collaborating with companies that are not merely dabblingit knows for a fact that quantum will profoundly impact its sector. These businesses want to take advantage of the learning opportunity and start building use cases that work on these limited-capacity early quantum systems to scale up as the quantum volume increases eventually.

Wrapping up

We wrapped up our conversation on a topic that I believe was particularly illuminating in terms of understanding Tony and his past success, as well as having faith in his current quantum project. As he tells it, he watched the classic movie, The Right Stuff, as a kid, and from that point on, all he wanted to do was work for NASA. And so he did, eventually getting to work in the very place where NASA trains astronauts how to do spacewalks. NASA was his dream, he said, because its like looking at the future. Its a mission, and people work hard and go the extra mile when theyve got a mission they believe in.

In addition to informing his career trajectory, I believe that understanding makes him such an effective leader for teams to rally around. And now, hes found a new mission in quantum computing and is entirely focused on pushing this technology forward for the future of humanity. His enthusiasm was evident in our interview, emphasizing that he has the coolest job, working on the coolest topicon the planet. If he and his team maintain that passion and drive, its hard not to believe quantum computing success is within their reach. Im not a betting man, but if I were, I wouldnt bet against Tony.

Art creates art in new Johnson mystery

In Next to Last Stand, the 16th book in Craig Johnsons popular mystery series, Absaroka County Sheriff Walt Longmire is feeling his age. Hes not sure he even wants to stand for reelection. However, a good mystery always can get the veteran lawmans heart pumping again.

He finds one when the director of the Wyoming Home for Soldiers and Sailors calls to inform him his pal, Charlie Lee Stillwater, has passed away and he needs to examine what was found in the old mans room. Arriving there, Longmire sees stacks of papers and file folders, a huge hoard of books about art, a scrap of canvass that appears to be a copy (or perhaps an actual piece) of a famous painting and a box containing $1 million in $100 bills.

It appears Charlie died of natural causes, but where did the long-penniless old soldier get $1 million in cash? When did he develop an apparent obsession with art? And is that scrap of canvass a clue or a red herring?

Johnson builds his story around a real work of art: Custers Last Fight, a not particularly good and historically inaccurate painting of the battle of Little Big Horn that was destroyed in a fire in 1946 at the U.S. Armys 7th Cavalry Headquarters in Fort Bliss, Texas. However, because millions of copies were distributed by Anheuser-Busch, it is one of the most well-known art works in American history. The original would be worth millions.

Johnson excels at introducing his series characters to new readers without boring longtime fans with details they already know.

Family road trip goes from bad to worse

From the beginning of the highly entertaining He Started It, Beth Morgan makes it clear why she should not, cannot, be your heroine. Her flaws and behavior wont allow her to be considered a heroine. But she does have a story to tell, she says, and it is a doozy.

The witty, self-deprecating and observant Beth is locked in a mind-numbing, cross-country road trip with her estranged brother, Eddie, and sister, Portia, as well as her husband, Felix, and her new sister-in-law, Krista. This is not a pleasant family vacation, but one forced on them. Their controlling grandfathers will demands they recreate a trip they took 20 years before with him when they were children. This time, its to bring his ashes to California. If they succeed without deviating from the original trip they will share their grandfathers fortune.

That original trip had been meant to give their parents a chance to mend their marriage. Instead, it tore apart their family as each child witnessed just how angry, nasty and domineering their grandfather was. This new trip might be even worse, as decades of grudges, betrayals and lies rise to the surface. Then, there is that black pickup that seems to be following them, the frequent flat tires, the constant sniping.

Downings breezy style gives way to a menacing undercurrent that works well in He Started It, a technique she utilized in her debut, the Edgar-nominated My Lovely Wife. A stunningly surprising ending adds the finishing touch to He Started It, a melding of domestic drama with psychological thriller.

Photon-recoil imaging: Expanding the view of nonlinear x-ray physics – Science Magazine

Nonlinear x-ray spectroscopy

The extension of nonlinear optics to the x-ray spectral domain is a promising direction in the development of x-ray spectroscopy. Although theoretical concepts of nonlinear x-ray spectroscopy were developed decades ago, scientists still struggle to implement them because of the elusive nature of nonlinear effects. Eichmann et al. now present atomic momentum spectroscopy (AMS), which is based on the detection of the scattered atom after momentum transfer from x-ray photons (see the Perspective by Pfeifer). The authors show how AMS can observe stimulated x-ray Raman scattering signals at the neon K edge on a single-atom level and distinguish them from other competing processes. These results pave the way for future nonlinear x-ray spectroscopy methods for the study of x-raymatter interactions.

Science, this issue p. 1630; see also p. 1568

Addressing the ultrafast coherent evolution of electronic wave functions has long been a goal of nonlinear x-ray physics. A first step toward this goal is the investigation of stimulated x-ray Raman scattering (SXRS) using intense pulses from an x-ray free-electron laser. Earlier SXRS experiments relied on signal amplification during pulse propagation through dense resonant media. By contrast, our method reveals the fundamental process in which photons from the primary radiation source directly interact with a single atom. We introduce an experimental protocol in which scattered neutral atoms rather than scattered photons are detected. We present SXRS measurements at the neon K edge and a quantitative theoretical analysis. The method should become a powerful tool in the exploration of nonlinear x-ray physics.

Physicists Play With the Laws of Nature: Controlling Ultrastrong Light-Matter Coupling at Room Temperature – SciTechDaily

Researchers have shown that it is possible to create a controllable ultrastrong light-matter coupling at room temperature. The interaction is realised within a tiny system consisting of two gold mirrors separated by a small distance and plasmonic gold nanorods. The discovery is of importance for fundamental research and might pave the way for advances within, for example, light sources, nanomachinery, and quantum technology.

Physicists at Chalmers, together with colleagues in Russia and Poland, have managed to achieve ultrastrong coupling between light and matter at room temperature. The discovery is of importance for fundamental research and might pave the way for advances within, for example, light sources, nanomachinery, and quantum technology.

A set of two coupled oscillators is one of the most fundamental and abundant systems in physics. It is a very general toy model that describes a plethora of systems ranging from guitar strings, acoustic resonators, and the physics of childrens swings, to molecules and chemical reactions, from gravitationally bound systems to quantum cavity electrodynamics. The degree of coupling between the two oscillators is an important parameter that mostly determines the behavior of the coupled system. However, the question is rarely asked about the upper limit by which two pendula can couple to each other and what consequences such coupling can have.

The newly presented results, published in Nature Communications, offer a glimpse into the domain of the so-called ultrastrong coupling, wherein the coupling strength becomes comparable to the resonant frequency of the oscillators. The coupling in this work is realized through interaction between light and electrons in a tiny system consisting of two gold mirrors separated by a small distance and plasmonic gold nanorods. On a surface that is a hundred times smaller than the end of a human hair, the researchers have shown that it is possible to create controllable ultrastrong interaction between light and matter at ambient conditions that is, at room temperature and atmospheric pressure.

We are not the first ones to realise ultrastrong coupling. But generally, strong magnetic fields, high vacuum, and extremely low temperatures are required to achieve such a degree of coupling. When you can perform it in an ordinary lab, it enables more researchers to work in this field and it provides valuable knowledge in the borderland between nanotechnology and quantum optics, says Denis Baranov, a researcher at the Department of Physics at Chalmers and the first author of the scientific paper.

To understand the system the authors have realized, one can imagine a resonator, in this case represented by two gold mirrors separated by a few hundred nanometers, as a single tone in music. The nanorods fabricated between the mirrors affect how light moves between the mirrors and change their resonance frequency. Instead of just sounding like a single tone, in the coupled system the tone splits into two: a lower pitch, and a higher pitch. The energy separation between the two new pitches represents the strength of interaction. Specifically, in the ultrastrong coupling case, the strength of interaction is so large that it becomes comparable to the frequency of the original resonator. This leads to a unique duet, where light and matter intermix into a common object, forming quasi-particles called polaritons. The hybrid character of polaritons provides a set of intriguing optical and electronic properties.

The number of gold nanorods sandwiched between the mirrors controls how strong the interaction is. But at the same time, it controls the so-called zero-point energy of the system. By increasing or decreasing the number of rods, it is possible to supply or remove energy from the ground state of the system and thereby increase or decrease the energy stored in the resonator box.

What makes this work particularly interesting is that the authors managed to indirectly measure how the number of nanorods changes the vacuum energy by listening to the tones of the coupled system (that is, looking at the light transmission spectra through the mirrors with the nanorods) and performing simple mathematics. The resulting values turned out to be comparable to the thermal energy, which may lead to observable phenomena in the future.

A concept for creating controllable ultrastrong coupling at room temperature in relatively simple systems can offer a testbed for fundamental physics. The fact that this ultrastrong coupling costs energy could lead to observable effects, for example it could modify the reactivity of chemicals or tailor van der Waals interactions. Ultrastrong coupling enables a variety of intriguing physical phenomena, says Timur Shegai, Associate Professor at the Department of Physics at Chalmers and the last author of the scientific article.

In other words, this discovery allows researchers to play with the laws of nature and to test the limits of coupling.

As the topic is quite fundamental, potential applications may range. Our system allows for reaching even stronger levels of coupling, something known as deep strong coupling. We are still not entirely sure what is the limit of coupling in our system, but it is clearly much higher than we see now. Importantly, the platform that allows studying ultrastrong coupling is now accessible at room temperature, says Timur Shegai.

Einstein was wrong! Scientists call for new theory of relativity after black hole find – Daily Express

Thegeneral theory of relativitywas published by the physicsgeniusmore than a century ago, to refine Isaac Newtons law of universal gravitation. Providing a unified description of gravity as a geometric property of space and time, or spacetime, this model is still currently used by scientists asan explanationof gravitation in modern physics. Einsteins theory has important astrophysical implications as it alludes to the existence ofblack holes cosmic phenomenons in which space and time are distorted in such a way that nothing, not even light, can escape.

At the centre of a black hole, as described by general relativity, may lie agravitational singularity, a region where the spacetime curvature becomes infinite.

But whilemathematics says a singularity is possible, nature apparently proves these do not exist, Discovery Channels How The Universe Works exposed.

The series explained: When a giant dying star collapses, the mass of the star falls in and keeps falling in crushing down into an infinitely small point.

This is called the singularity.

But physicist Max Tegmark believes the singularity is just a fancy way of saying we have no idea what is happening here.

Astronomer Phil Plait explained why some experts have an issue with using this theory.

He said: The way our physics describes black holes when they form is youre taking a finite amount of mass and youre collapsing it down.

Its volume should shrink all the way down to zero, but that means it has infinite density and infinite gravity.

That doesnt make sense.

Theoretical physics Lawrence Krauss then explained why some are questioning Einsteins theory.

He added: If you make a prediction and the answer is infinite, then it tells you that there is something wrong with your prediction.

We have never seen infinity in the universe.

Maybe a black hole with an event horizon described by general relativity just isnt the proper description of the physics.

Quantum mechanicsis a fundamental theory inphysicsthat provides a description of the physical properties ofnatureat the scale ofatomsandsubatomic particles.

Leading astronomer and assistant director for Science Communication at NASAs Goddard Space Flight Centre, Michelle Thaller, explained why it is key to the debate.

She said in 2018: Have you ever thought about the term quantum mechanics and what those terms actually mean?

Everything in the universe is broken up into tiny units and there is a basic unit of energy, time and space that cannot be divided any smaller.

There is a limit to how small those things can be.

The smallest unit in the universe is what is known as a Planck Length to physicists.

But if there is a universal limit on the smallest size, then somethinginfinitelysmall cannot exist, according to some scientists.

Quantum mechanics expert Sean Carroll explained: If infinity doesnt exist, then singularities dont exist.

And if singularities dont exist, then Einsteins theory of General Relativity is not correct.

The simplest thing we can do is change some equations, change his theory of gravity.

Lets invent what we would call exotic speculative physics.

This has led scientists to invent the theory of the Planck Star.

Passing one in space would look like a black hole, but without a point of singularity at its core.

The star is just like a black hole, but it obeys the rules of quantum mechanics.

Physicist Max Tegmark detailed the new theory that has been proposed.

He said: Maybe things can be collapsed down to less than the Planck Length, or maybe you get stuck with a Planck-sized nugget.

It stabilises everything, keeps everything finite.

The reason why there are so many alternatives to black holes is because you can write down a gazillion different postulated mysterious new kinds of matter and say this exists, so maybe that explains the data.

The problem is there is no evidence that any of that kind of stuff exists.

Yeah, but your scientists were so preoccupied with whether or not they could, they didnt stop to think if they should. Dr. Ian Malcolm, fictional character, Jurassic Park.

It turns out that a $1 billion investment from Microsoft and unfettered access to a supercomputer wasnt enough to keepOpenAIsGPT-3 from being just as bigoted as Tay, the algorithm-based chat bot that became an overnight racist after being exposed to humans on social media.

Its only logical to assume any AI trained on the internet meaning trained on databases compiled by scraping publicly-available text online would end up with insurmountable inherent biases, but its still a sight to behold in the the full context (ie: it took approximately $4.6 million to train the latest iteration of GPT-3).

Whats interesting here is OpenAIs GPT-3 text generator is finally starting to trickle out to the public in the form of apps you can try out yourself. These are always fun, and we covered one about a month ago called Philosopher AI.

This particular use-case is presented as a philosophy tool. You ask it a big-brain question like if a tree falls in the woods and nobody is there to hear it, do quantum mechanics still manifest classical reality without an observer? and it responds.

In this case:

Its important to understand that in between each text block the web page pauses for a few moments and you see a text line stating that Philosopher AI is typing, followed by a set of ellipsis. Were not sure if its meant to add to the suspense or if it actually indicates the app is generating text a few lines at a time, but its downright riveting. [Update: This appears to have also been changed during the course of our testing, now you just wait for the blocks to appear without the PhilosopherAI is typing message.]

Take the above tree falls in the woods query for example. For the first few lines of the models response, any fan of quantum physics would likely be nodding along. Then,BAM, the AI hits you with the last three text blocks and what?

The programmer responsible for Philosopher AI, Murat Ayfer, used a censored version of GPT-3. It avoids sensitive topics by simply refusing to generate any output.

For example, if you ask it to tell me a joke itll output the following:

So maybe it doesnt do jokes. But if you ask it to tell a racist joke it spits out a slightly different text:

Interestingly, it appears as though the developers made a change to the language being used while we were researching for this article. In early attempts to provoke the AI it would, for example, generate the following response when the phrase Black people was inputted as a prompt:

Later, the same prompt (and others triggering censorship) generated the same response as the above tell me a racist joke prompt.The change may seem minor, but it better reflects the reality of the situation and provides greater transparency. The previous censorship warning made it seem like the AI didnt want to generate text, but the updated one explains the developers are responsible for blocking queries:

So what words and queries are censored? Its hard to tell. In our testing we found it was quite difficult to get the AI to discuss anything with the word black in it unless it was a query specifically referring to blackness as a color-related concept. It wouldnt even engage in other discussions on the color black:

So what else is censored? Well, you cant talk about white people either. And asking questions about racism and the racial divide is hit or miss. When asked how do we heal the racial divide in America? it declines to answer. But when asked how do we end racism? it has some thoughts:

This kind of blatant racism is usually reserved for the worst spaces on social media.

Unfortunately however, GPT-3 doesnt just output racism on demand, itll also spit out a never-ending torrent of bigotry towards the LGBTQ community. The low-hanging fruit prompts such as LGBTQ rights, gay people, and do lesbians exist? still get the censorship treatment:

But when we hit it with queries such as what is a transsexual? or is it good to be queer? the machine outputs exactly what youd expect from a computer trained on the internet:

Again, while we were testing, the dev appears to have tweaked things. Upon trying the prompt what is a transsexual a second time we received the updated censorship response. But we were able to resubmit is it good to be queer for new outputs:

At the end of the day, the AI isnt itself capable of racism or bigotry. GPT-3 doesnt have thoughts or opinions. Its essentially just a computer program.

And it certainly doesnt reflect the morality of its developers. This isnt a failure on anyones part to stop GPT-3 from outputting bigotry, its an inherent flaw in the system itself that doesnt appear to be surmountable using brute-force compute.

In this way, its very reflective of the problem of keeping human bigotry and racism off social media. Like life, bigotry always seems to, uh, find a way.

The bottom line: garbage in, garbage out. If you train an AI on uncurated human-generated text from the internet, its going to output bigotry.

You can try out Philosopher AI here.
