As a venture capitalist, Jim Breyer has invested in many breakthrough technology ideas in recent decades, names we all know and interact with on a daily basis like Meta and Spotify. But the biggest one of all may be next, he says, through the combination of artificial intelligence and branches of science involved in medicine.
Since 2017, Breyer says his No. 1 task as a venture investor has focused on finding the best disease and medical data from leading research hospitals such as Memorial Sloan Kettering, MD Anderson, and Johns Hopkins highly proprietary, significant data to license into startups Breyer Capital is backing.
"AI and medicine is perhaps the most attractive new investment opportunity I've ever seen," Breyer, founder and CEO of Breyer Capital, said at last week's CNBC Healthy Returns virtual summit.
Breyer says he is not alone among tech leaders holding this view, citing a fireside chat he recently conducted with Michael Dell, during which the PC pioneer agreed, and private conversations he has had with tech CEOs. "Over the last 12 months, mega-cap companies, based on direct meetings with Satya [Nadella, Microsoft CEO] and Tim Cook [Apple CEO] and others are not just doubling, tripling down on health care and medicine, it's 10x, 50x," Breyer said.
But the opportunity won't translate into achievement without a new form of collaboration between the classic big tech talent and the medical field.
"Bringing together the brilliant 32 or 35-year-old machine learning people out of Amazon or Google or Microsoft and having them work closely with Nobel-winning doctors and great hospitals and great medical specialists is really challenging, but that's where breakthrough investment returns will be in both public and private companies," Breyer said.
Dr. Sanjiv Patel, president &CEO of Relay Therapeutics, which works at the intersection of new experimental techniques for drug discovery and computational science, says unlike the "false dawns" over the past few decades, it is for real this time. "It's no longer science fiction, we have three in clinical trials," Patel said.
But he cautioned that change will face many obstacles and an uncertain timeline. "There is a lot of hype. People say you push a button in the metaverse and get a life-changing medicine, and I just don't think were there," Patel said. "We are looking at incremental change over time ... and there are some significant challenges to overcome."
Some of those challenges will be case-specific as AI attempts to transform healthcare across the entire value chain; some will relate to the general problem of high quality, clean data sets "that's not easy to get," he says; and a third will be the bridging of the scientific talents cited by Breyer.
"The availability of bilingual scientists is going to be a rate limitation for us," Patel said, defining this as scientists well versed in computation research and one of the core sciences important to medicine physics, biology or chemistry. "That's a big one," he said.
All knowledge industry workers should assume they will need AI technology and remain open-minded about its use, says Dr. Vineeta Agarwala, Andreessen Horowitzgeneral partner. One of her portfolio companies, Insitro, was founded by Stanford AI researcher Daphne Koller (Koller co-founder edtech company Coursera). She cited an example Koller has been using of workers 30 years ago who said they didn't need personal computing technology when it was becoming more mainstream. "It would have been crazy for the knowledge industries to say 'We're okay. We're doing okay the way we are,'" Agarwala said at CNBC Healthy Returns.
Her VC is "on the prowl," she says, for founders who say they want to use AI to augment what they can do, so they can do more. "That's how we look at it, the companies and the researchers and the entrepreneurs," Agarwala said. "Embracing AI should look a little like those that embraced computers a few decades ago ... it will be inconceivable in the future to not be embracing this."
Unlike the evolution of the PC, which took three decades, she expects in the case of AI this will be "obvious" within five to ten years.
As a doctor, Agarwala says the amount of medical information she needs to stay on top of is already at "fever pitch," from medical literature to clinical trials and learnings from large sets of patient data. And she noted Microsoft already has integrated ChatGPT with its medical dictation software for doctors. These kinds of AI bridges will help with immediate workflow issues which contribute to physician burnout. "Just in the workflow of seeing patients and interfacing with the payer ecosystem, there may be a way for large language models to contribute to a reduction in burnout," she said.
After that, comes the "real biology," she says.
Already, AI is being applied to make better decisions for medicinal chemistry teams to pick better molecules or predict in advance toxicity of certain molecules, and over the next five to 10 years, expect talent that chooses to use AI to augment their role to have this "super power," Agarwala said.
"It's not can AI do what a human expert is doing but relentless focus on where AI can give me insight no human could have had," she said. "There is lots of exciting big talent opportunities coming from big tech and big cap pharma," she said. "Both need to come together to create companies."
Cloud services run by big tech companies including Microsoft and Amazon (Amazon Web Services) will be beneficiaries in the immediate years ahead, but for workers already at these companies which have made steep job cuts over the past year, including some job cuts reaching nascent health science efforts Breyer is focused on the mid-career talent that see where AI and medicine are going together.
"The single biggest challenge, day to day, week to week, for me is to bring the interdisciplinary individuals and teams together ... biotech, computation, specialized chemistry ... and have them all working together," Breyer said.
"The talent I see are the 30 to 35-year-old alumni of these companies, Meta, Microsoft and Alphabet, that want to go into this field on a mission, either through personal family history or view of the opportunity, this is where they want to spend the rest of their careers," Breyer said. "And rarely have I seen the 10-year alums of these mega caps saying this."
As Breyer goes out to speak with the next generation of professionals, students at schools including UT Austin, Harvard, Stanford, and Columbia, his message is clear: "This is the single biggest opportunity I've seen. However, make sure you are studying linear algebra and computation and chemistry and biology, because all of the fundamental opportunities are about these technologies that sit at the intersection of computation and science."

Science fair brings brightest students from across the region – Rome Sentinel
UTICA Utica University held its 44th annual Regional Science Fair on Saturday, April 1, bringing together some of the brightest students from the Mohawk Valley.
Students from Clinton, Poland, Remsen, Rome, Utica and Whitesboro school districts, along with the Utica Academy of Science Charter School had their science projects on display in the Donahue Concourse, underneath the Frank E. Gannett Memorial Library.
Since 1978, the science fair has taken place with a mission to bolster math and science programs across the Mohawk Valley and to encourage students to pursue their academic interests in STEM education.
Student projects were categorized by grades 7 and 8 in the junior level and grades 9 through 12 in the senior level. Student projects were also categorized under three topics: physical science, natural science, and math, engineering, and computer science.
Volunteer judges from local colleges, the technology and research industries, as well as medical professionals and civilian and military staff members, examined every project on display prior to allowing the public into the exhibit area and to learn about the projects from the students.
"The future is very bright with all of you at the helm of science and STEM," Jessica Thomas said to the students participating in this year's science fair. Thomas, a professor of biology at Utica University, serves as the director of the regional science fair.
First through fourth-place winners took home cash awards ranging from $25 to $100 and a certificate, medal, and ribbon recognizing their accomplishments. The Grand Champion - Junior Level winner was awarded a $500 tuition-remitted scholarship to Utica University for one year, along with a trophy and certificate. The runner-up Grand Champion - Senior Level was awarded a half-tuition scholarship to Utica University for one year, along with a trophy and certificate. The Grand Champion - Senior Level was awarded a half-tuition scholarship to Utica University for two years, as well as a trophy and certificate.
As the winner of the university's Grand Champion - Senior Level prize, Angelina Le will also be invited to compete in the 2023 Regeneron International Science and Engineering Fair in Dallas, Texas, next month. Utica University will be sponsoring her and a chaperone to participate in the event. Should Le not be able to participate, Dennis van Hoesel, the runner-up, will be invited to compete.
"I hope that all of this is one moment in time in your young science careers that will encourage you to continue to think critically and reflectively about the world around you," Todd Pfannestiel, provost and vice president at Utica University, remarked to the students. "It's your efforts displayed here today that self-empower you to act responsibly for a better community throughout the rest of your lives."

University of Idaho: Preparing students for the 21st century – Study International News
At the University of Idaho (U of I), passion sparks real impact. As an institution, the university pioneered a research-driven and innovative approach to delivering lessons in engineering, computer science and cybersecurity. Today, students at U of I are spearheading breakthroughs in their respective fields.
Christopher Bitikofers innovation aptly represents the universitys engineering prowess. The mechanical engineering Ph.D. graduate worked with a team of students and faculty members to develop a complex robotics exoskeleton used in therapeutic medicine.
The exoskeleton mimics a human arms movement and abilities to help stroke survivors regain mobility. It focuses on two areas of motion the elbow and forearm. Currently, Providence St. Lukes Rehabilitation Medical Center in Spokane, Washington, is testing this exoskeleton with its patients.
Bitikofers visions came to be at the Assistive Robotics Lab, a state-of-the-art, hands-on learning space where engineering students develop robotic devices that evaluate neurological impairment, gather data to refine therapeutic medicine, and exponentially improve treatment for the greater good.
Using my engineering degree to make positive change, this is one of the most effective ways for me to spend my time, said the mechanical engineering PhD graduate. Working alongside physical therapists and hospital staff and developing these devices, were helping people improve their independence.
Bitikofers work proves that opportunities abound for anyone who pursues engineering at U of I, and undergraduates are no exception. At its core, the B.S. Mechanical Engineering teaches students to apply their maths, science, and engineering knowledge to research, design, and test devices or processes.
The program is one of many in the College of Engineering that unlocks exceptional learning, training, and research experiences. For 130 years, the division has provided just that and more through its departments: Chemical and Biological Engineering, Civil and Environmental Engineering, Computer Science, Electrical and Computer Engineering, Mechanical Engineering and Nuclear Engineering & Industrial Management.
With over a century of experience, the college and its departments remain relevant in the modern age by adapting its offerings to tackle new global problems. For example, U of Is College of Engineering recently launched Idahos first undergraduate degree program in cybersecurity.
With the B.S. Cybersecurity, aspiring cybersecurity professionals gain a better understanding of how to deal with cybersecurity threats through simulation. The Real-Time Digital Simulator (RTDS) connected to a local control hub in the Integrated Research and Innovation Center can simulate any modern high-voltage power grid configuration. With this, students can mimic control operations and simulate what a cyberattack might look like.

The End of Programming Is Nigh – The New Stack
Is the end of programming nigh?
If you ask Matt Welsh, hed say yes. As Richard McManuswrote on The New Stack, Welsh is a former professor of computer science at Harvard who spoke at a virtual meetup of theChicago Association for Computing Machinery (ACM), explaining his thesis that ChatGPT and GitHub Copilot represent the beginning of the end of programming.
Welsh joined us on The New Stack Makers to discuss his perspectives about the end of programming and answer questions about the future of computer science, distributed computing, and more.
Welsh is now the founder of Fixie.ai, a platform they are building to let companies develop applications on top of large language models to extend with different capabilities.
For 40 to 50 years, programming language design has had one goal. Make it easier to write programs, Welsh said in the interview.
Still, programming languages are complex, Welsh said. And no amount of work is going to make it simple.
It doesnt seem likely to me that any amount of work on improving type systems or syntax or any of that debugging is going to suddenly crack that nut and just make programming suddenly easy, Welsh said. Weve been at it for a while. Its not improving. So this is where I think theres going to have to be a kind of a quantum shift to not programming anymore as the way to talk to computers and instruct them.
Its comparable to when, for example, only a few people could read books.
Well, if computing becomes, lets say, democratized, because now you dont need to be this like wizard in a tower, who understands how to write Rust code, to instruct a machine, thats going to completely change that dynamic, Welsh said. Anyone will be able to do it. And I actually think thats a really good thing. You know, theres all kinds of people in the world and places in the world that could benefit from computing that simply do not have access to it, because the skill level, the skill set required is just way too high.
As for computer science, it has always been about humans taking a problem and turning it into instructions for a machine, Welsh said. Thats the definition of computer science. Its the art of science, mapping problems onto what machines can do. Now that models are getting larger, its no longer an x86 CPU running the machine instruction.
So now your computational core is no longer an x86 CPU running machine instructions, Welsh said. Its an AI model that is solving problems. And, you know, operating and working in the ways that like a human might, in a lot of ways.

Opinion | Colleges Should Be More Than Just Vocational Schools – The New York Times
Never mind that neither politicians nor students seem to have a particularly good idea of which college majors will actually prepare young people for the work force. History majors had a lower unemployment rate than economics, business management or communications majors, and their salaries barely lag behind in those fields, according to a recent study. Art history majors do just fine, too, with strong projected job growth in the next decade. And despite the sneers, those with bachelors degrees in philosophy have an average salary around $76,000, according to PayScale. But this is a grim and narrow view of the purpose of higher education, merely as a tool to train workers as replaceable cogs in Americas economic machine, to generate raw material for its largest companies.
Higher education, with broad study in the liberal arts, is meant to create not merely good workers but also good citizens. Citizens with knowledge of their history and culture are better equipped to lead and participate in a democratic society; learning in many different forms of knowledge teaches the humility necessary to accept other points of view in a pluralistic and increasingly globalized society.
The university as we know it emerged in the Middle Ages, founded around the study of rhetoric, grammar, logic, astronomy, mathematics, geometry and music or what the Romans called artes liberales, meaning the arts of free people. The first three disciplines evolved into the modern humanities and arts; the others evolved into natural and social sciences.
It was Cold War-era American nationalism that reframed this course of study, once available only to the wealthy few, as something essential for American success. In 1947 a presidential commission bemoaned an education system in which a student may have gained technical or professional training while being only incidentally, if at all, made ready for performing his duties as a man, a parent and a citizen. The report recommended funding to give as many Americans as possible the sort of education that would give to the student the values, attitudes, knowledge and skills that will equip him to live rightly and well in a free society, which is to say the liberal arts as traditionally understood. The funding followed.
The report is true today, too. There is still value in our health professionals knowing something about literature, our financial professionals knowing something about history and our political leaders knowing something about ethics. But as that funding is dismantled, the American higher education system is returning to what it once was: liberal arts finishing schools for the wealthy and privileged and vocational training for the rest.

What Is Abstraction In Computer Science? – Dataconomy
What is abstraction in computer science? Abstraction is the magical art of simplifying the most complex of computer systems, unlocking their power and secrets. Its like finding a hidden treasure by filtering out the irrelevant details and focusing on what matters the most. In other words, abstraction is the process of creating a birds-eye view of a system, allowing programmers to break it down into smaller, more manageable pieces.
Abstraction plays a fundamental role in computer science, providing the necessary building blocks for creating modular, efficient, and reusable code. By using abstraction, programmers can unlock their creativity, create innovative solutions, and explore the most intricate corners of the digital world.
Whether youre building software applications, designing computer architecture, or working on digital circuits, abstraction is the key to success. It enables you to simplify complexity, manage change, and create systems that are both powerful and elegant. So, lets embrace abstraction, and unleash the full potential of computer science!
In general, abstraction refers to the act of representing complex systems or ideas in a simplified way that can be easily understood. In computer science, abstraction is a fundamental concept that involves breaking down complex programming problems into smaller, more manageable parts. This allows developers to create more efficient, modular code that can be easily maintained and updated.
In essence, abstraction involves hiding complexity and focusing on the essential aspects of a problem. For example, a programmer might abstract away the low-level details of hardware interactions in order to focus on developing higher-level software components. This allows the programmer to create more reusable code that can be used in a variety of contexts.
Abstraction in computer science is a way of simplifying complex systems by breaking them down into smaller, more manageable parts. In programming, abstraction involves creating classes, functions, and other building blocks that can be combined to solve larger problems.
One important aspect of abstraction in computer science is the idea of abstraction layers. These layers are used to separate different levels of complexity in a system, allowing programmers to focus on one layer at a time. For example, a software developer might work on the user interface layer of an application, while another developer works on the data layer. This allows each developer to focus on their area of expertise without being overwhelmed by the entire system.
Data governance 101: Building a strong foundation for your organization
Data abstraction is a specific type of abstraction that involves simplifying data structures in order to make them easier to work with. In computer science, data abstraction involves creating abstract data types (ADTs) that hide the implementation details of a particular data structure.
For example, a programmer might create an ADT for a stack data structure, which would provide a set of operations (such as push, pop, and peek) that can be used to manipulate the stack. The ADT would hide the details of how the stack is implemented, allowing the programmer to use the stack without worrying about the low-level details.
Control abstraction is another type of abstraction that involves simplifying control structures (such as loops and conditionals) in order to make them easier to use. In computer science, control abstraction is often used in the context of programming languages.
For example, many programming languages provide higher-level control structures (such as foreach loops and switch statements) that allow developers to write more concise and expressive code. These control structures hide the details of how the loop or conditional is implemented, making it easier for developers to focus on the higher-level logic of their programs.
Procedural abstraction is a type of abstraction that involves breaking down a program into smaller procedures or functions. This allows developers to create reusable code that can be called from different parts of a program.
For example, a programmer might create a function that calculates the average of a set of numbers. This function can then be called from different parts of the program, allowing the programmer to reuse the same code without having to write it multiple times. This makes the code more efficient and easier to maintain.
Abstraction is a crucial concept in computer architecture, as it allows designers and engineers to create complex systems that are easier to understand and manage. In computer architecture, abstraction refers to the use of layers or levels of detail to simplify the design of a system.
For example, a computer system can be abstracted into several layers, such as the hardware layer, the operating system layer, and the application layer. Each layer is designed to provide a certain level of functionality, while hiding the details of how the underlying system works.
By using abstraction in computer architecture, designers can create systems that are more modular, easier to maintain, and more flexible. Abstraction also allows for greater innovation, as designers can create new systems and technologies without having to start from scratch each time.
In computer science, there are several levels of abstraction that are used to simplify complex systems. These levels include:
Each level of abstraction provides a higher-level view of the system, while hiding the details of the lower-level layers. This allows programmers and designers to focus on their area of expertise, without being overwhelmed by the complexity of the entire system.
The software domain refers to the area of computer science that is focused on developing software applications. This includes programming languages, software development tools, and software engineering methodologies.
In the software domain, abstraction is a fundamental concept that is used to simplify complex software systems. This involves breaking down software applications into smaller, more manageable components, such as functions, classes, and libraries. By using abstraction, software developers can create more modular and reusable code, which is easier to maintain and update over time.
The digital domain refers to the area of computer science that is focused on digital electronics and digital systems. This includes digital circuits, digital signal processing, and digital communication systems.
In the digital domain, abstraction is used to simplify the design of digital systems. This involves breaking down complex digital circuits into smaller, more manageable components, such as logic gates, flip-flops, and registers. By using abstraction, digital designers can create more efficient and reliable systems, which are easier to debug and test.
The analog domain refers to the area of computer science that is focused on analog electronics and analog systems. This includes analog circuits, analog signal processing, and analog communication systems.
In the analog domain, abstraction is used to simplify the design of analog systems. This involves using mathematical models to represent the behavior of analog circuits and systems, which allows designers to analyze and optimize their performance. By using abstraction, analog designers can create more efficient and reliable systems, which are easier to design and test.
Abstraction and encapsulation are two important concepts in object-oriented programming, and they are often used interchangeably. However, they are not the same thing, and it is important to understand the differences between them.
Abstraction is the process of identifying the essential features of an object or system, while ignoring the non-essential or irrelevant details. In the context of object-oriented programming, abstraction is achieved by defining abstract classes and interfaces that provide a high-level view of a system or object, without specifying the details of how it works.
Abstraction is used to simplify complex systems by breaking them down into smaller, more manageable components. By using abstraction, software developers can create modular, reusable code that can be used in a variety of contexts.
For example, consider a program that simulates a zoo. The program might define an abstract class called Animal that provides a high-level view of what an animal is, without specifying the details of each individual animal. The Animal class might define methods such as eat, sleep, and move, which are common to all animals. Concrete classes such as Lion and Elephant can then be derived from the Animal class, and they can implement the methods in their own way.
Microcomputers: The miniature wonders of modern technology
Encapsulation is the process of hiding the implementation details of an object or system, while exposing a public interface that can be used by other objects or systems. Encapsulation is achieved by defining classes that have private data members and public methods that operate on those data members.
Encapsulation is used to protect the internal state of an object or system, and to prevent other objects or systems from accessing or modifying that state directly. This helps to ensure the integrity of the system, and it makes it easier to modify or update the system in the future.
For example, consider a program that simulates a bank account. The program might define a class called Account that has private data members such as balance and accountNumber. The Account class might also define public methods such as deposit and withdraw, which can be used to manipulate the balance of the account. Other objects or systems can interact with the Account class by calling its public methods, but they cannot access or modify the private data members directly.
Abstraction and encapsulation are related concepts, but they serve different purposes. Abstraction is used to simplify complex systems by breaking them down into smaller, more manageable components, while encapsulation is used to protect the internal state of an object or system.
Abstraction is achieved by defining abstract classes and interfaces that provide a high-level view of a system or object, while encapsulation is achieved by defining classes that have private data members and public methods.
Abstraction and encapsulation are both important concepts in object-oriented programming, and they are often used together to create modular, reusable, and maintainable code. By understanding the differences between them, software developers can create more effective and efficient systems that meet the needs of their users.
What is abstraction in computer science? Well, as we read earlier, abstraction is the process of simplifying complex systems by breaking them down into smaller, more manageable parts. It involves identifying the essential features of a system, while ignoring the non-essential or irrelevant details.
Through abstraction, programmers can create modular, efficient, and maintainable code, allowing them to build innovative solutions and explore new horizons. Abstraction enables us to create high-level views of systems, providing a birds-eye perspective that helps us to manage complexity and focus on what matters most.
In short, abstraction is a fundamental concept in computer science, providing the building blocks for creating elegant and powerful systems. Whether youre a software engineer, a computer architect, or a digital designer, abstraction is your secret weapon for unlocking the full potential of the digital world. So embrace abstraction, simplify complexity, and create systems that are both beautiful and functional.
Abstraction in computational thinking refers to the process of simplifying complex problems or systems by breaking them down into smaller, more manageable parts. It involves identifying the key features of a problem or system, and ignoring irrelevant or non-essential details.
In computational thinking, abstraction is a fundamental concept that allows people to analyze and solve problems more efficiently. By using abstraction, people can focus on the most important aspects of a problem, and create more effective and efficient solutions.
For example, a computer scientist might use abstraction to break down a complex algorithm into smaller, more manageable components, such as functions or subroutines. This makes the algorithm easier to understand and modify, and it makes it more efficient to execute.
Abstraction is important in computer science for several reasons. First, it allows programmers to create more efficient and maintainable code by breaking down complex problems into smaller, more manageable components. This makes it easier to write, debug, and modify software applications.
Second, abstraction helps to promote modular design, which is a key principle of software engineering. By using abstraction, programmers can create reusable code that can be used in a variety of contexts, reducing the amount of time and effort required to develop new software applications.
Finally, abstraction is important in computer science because it enables innovation. By creating abstract models of complex systems, programmers can explore new ideas and develop new technologies without being limited by the constraints of existing systems.
Abstraction plays a critical role in software engineering, as it allows programmers to create modular, reusable, and maintainable code. By using abstraction, programmers can break down complex software applications into smaller, more manageable components, such as functions, classes, and libraries.
This makes it easier to develop and maintain software applications over time, as each component can be developed and tested separately, without affecting the other components. It also makes it easier to reuse code across different software applications, reducing the amount of time and effort required to develop new software.
In addition, abstraction is important in software engineering because it allows programmers to create abstract models of software systems, which can be used to analyze and optimize their performance. By using abstraction, software engineers can identify the key features of a system, and optimize them to improve the overall performance of the system.
Abstraction is a fundamental concept in software engineering, and it plays a critical role in the development of software applications and systems.
