Why does Andrew argue that biology can’t be reduced to simple cartoon diagrams?

Andrew White 0:00
You will never be able to reduce biology to like these cartoon diagrams. There is like complexity at every single level and it always plays a role. So I think it's a a domain which is driven by observations and empirical measurements, rather than a domain that's driven by like some sort of virtual in silico model that you can drive. I think c sort of stops this, I don't know, ASI or AGI hypothesis that like a model that's so intelligent could just wake up one day and know how to cure cancer by just thinking through it. Sometimes it seems like we can solve the problems with empirical, like machine learning models. Sometimes it thinks we looks like we can solve first principle methods. And I I don't know.

The only thing that does work 100% of the time is measuring it in the lab. And maybe all these methods are just approximations, and all they can do is increase your hit rate or decrease the number of experiments you have to do in a loop in the lab. Future House is really Sam Rodriguez's uh brainchild, I think. Sam came up with this idea. Which is basically like an FRO. Like we want to be at the scale of that level, like twenty and fifty million dollars and like a few year time scale. But it's not like a five-year goal. It's like a moonshot project that you may not accomplish in five years, or maybe you will know if you can accomplish it in five years, and then you'll need to go get more money to do it, or it'll be

commercializable at that time. Hello, and welcome back to the cognitive revolution. Today I am excited to share my conversation with Andrew White, Professor of Chemical Engineering at the University of Rochester, and now co founder and head of science at Future House, an Eric Schmidt backed focused research organization that's building increasingly autonomous AI systems to accelerate scientific discovery. We begin by briefly discussing Andrew's background in statistical mechanics and molecular simulation, how his AI journey began during a 2019 sabbatical, how he came to write a textbook on deep learning for molecules and materials, and ultimately to his involvement with OpenAI's GPT-4 RED team in 2022, which is where we had first crossed paths.

From there we unpack two of Future House's major recent releases Paper QA and Aviary. Paper QA is a question answering framework that works across entire bodies of scientific literature, using a mix of techniques including keyword expansion, full text search, contextual summarization, and large language model powered relevance filtering to achieve superhuman performance on question answering, contradiction detection, and Wikipedia style citation supported topic summary writing. Here, Andrew emphasized Future House's philosophy of optimizing for results rather than efficiency. They are willing to spend whatever compute or token budget is required and to wait for however many seconds are required to achieve the best possible output.

This quality first approach, as you'll hear, is one that I think a great many AI builders should take inspiration from. Aviary, meanwhile, Future House describes as a gymnasium framework for training language model agents on constructive tasks. In addition to creating conceptual clarity by distinguishing between agents, which contain core models and memory, and their environments, which provide tools and interfaces. This project introduces an interesting representation of agent systems as stochastic computation graphs, and very interestingly shows how agent systems can be trained end to end even when black box commercial models are used at key nodes. I found Andrew to be so thoughtful in his responses, and he was sufficiently generous with his time, that I took the opportunity to ask a bunch of related questions along the way as well.
Nathan Labenz 3:30
One answer that continues to rattle around in my head was Andrew's argument that because better conceptual frameworks and automation platforms are quickly reducing the cost of real world experimental work, perhaps machine learning models' ability to run experiments in silico will ultimately prove less transformative than I had been expecting.
