I wrote a post talking about how it would be useful if graduate programs/students (and also AI labs) thought differently about what skills they’re actually developing/automating in science and ask whether they’re the right ones. I personally think PhDs are still valuable. Arcadia pretty much exclusively hires them… some of the most creative and generative I’ve ever met. That said I strongly suspect our talent pool will shift as academia gets lapped from its resistance to change at a time when the status quo is no longer an option. None of us can see very far into the future right now, so things that take a long time (like a PhD) are inherently of uncertain value. That said, everything we do right now provides an opportunity to level up. I’m quite sure the only wrong answer is staying the course and not questioning our assumptions open.substack.com/pub/pracheeac/…

Lucy Maud Montgomery (of Anne of Green Gables fame) published Emily of New Moon in 1923. In it is this exchange: “I wish I could say something clever at the right time,” said Emily wistfully. “I always say exactly what I think at the time,” said Ilse, “and then I always wish I hadn’t.” I am Ilse.

Hey are any of you faculty hiring committees leveraging state of the art AI tools (not several generations behind) to traverse your past workflows with greater depth and see if it would have made similar or different decisions to unearth candidates for your long/short lists? yes yes the world is ending -- we must hold as sacrosanct the highly sophisticated triage mechanism of ....counting papers and.... sorting by journal name. Even without incorporating any of these tools yet, has anyone done a retrospective on choices/filtering already made by humans?

@PracheeAC Turns out people have studied the topic for centuries and that matters but cool beans have an electrical engineer perform your colonoscopy. You can’t even get an argument straight. Sorry

Sometimes I wonder how so many PhDs have a massive blind spot for epistemology — because it’s not like we didn’t teach it. So I suspect it’s because we let careerism supplant intellectual curiosity and they no longer give a fuck

@carletone6 Wow! Maybe not everyone is as focused on pedigree as skills and outcomes. You’re making my point that lots of scientists prefer pedigree and proxies for truth over whether they’re adhering to the uncertainty in how knowledge is generated

AI isn’t the only thing that has a generalization problem. The people who will cite an impactful scientific outcome and extrapolate it to justify their self-interested careerist nonsense under the vague aspiration of societal advancement also have a generalization problem

@Smark_phd Probably except we don’t really capture the lessons or trajectory that well and instead just the tidy explanations so we may have to incorporate domain constraints rather than rely only on the data available

@PracheeAC If science is the closest thing humanity has had to a collective-human system of "not fooling ourselves" (Popperian falsification). Then... Do you think the lessons we've learned about how science has gone wrong could help us build AGI?

Kind of interesting how people who have fully abdicated to journal editors their scientific judgment, entire trajectory of their field, how their colleagues and students are hired/judged are worried AI is the biggest threat to independent thinking

@DrEmmaZang Why do we need journals. No longer for publishing. Review, inferior to downstream work and whether it holds up. Curation tools are also better than ever. Worst thing we ever did is abdicate our judgement and insight about quality to journal editors

Surprises me *not at all* that the generative lack a scarcity mindset around protecting their ideas. It’s hard enough to get important shit done when you shout it from the rooftops and invite the contributions of other mission-aligned, creative, ambitious, hyper-competent folks. The cagey have zero chance
Niko McCarty.@NikoMcCarty

When I launched the "Fast Biology Bounties" (on a whim) with $10,000 in prizes, people told me that I would not get any ideas because people wouldn't want to share them, or all the good ideas were already being developed, etc. This is definitely not true. I've gotten >400 submissions and at least 20 really creative, original, tractable ideas. Many of the best ideas came from people who are *super generative*, meaning they sent me multiple ideas, most of which were good. And when I asked them if it's OK for me to share their ideas, they almost always said "yes." Ideas are cheap, in other words. Smart people tend to have lots of them, and are bottlenecked by time and resources to execute. I guess I already knew this, but now I have much more evidence for it. I don't know if I'll do one of these bounties again. If ideas are truly cheap and execution is the bottleneck, then perhaps I should just give grants to people who already have a good idea but need a $5-$20k grant to reach a technical milestone. I'll start sending out some of the best ideas I received on my blog. A deeper retrospective quantifying everything I learned is also coming soon at nikomc.com //

This articulation is super helpful framing because it gets at a thing I also see on the front lines of drug discovery research. Namely that when we say AI dramatically accelerates the work, a key aspect is decreasing friction of cross-team collaboration. A clear example I see this happening for us is bridging the gap between the frontier computational scientists/theorists and experimentalists such that we don’t have to productionize computational workflows for broader internal use that are still under active tinkering/development. The iteration becomes tighter to experimentally test computational predictions while simultaneously improving and innovating on the computational approaches. The productionization by software engineers can happen downstream when we have greater confidence and experimental validation of the approach but now also with reduced tech debt or improved ability to deal with it. Other places I can imagine AI acceleration is giving computational folks greater intuition on the timescales, difficulty, and reliability of various experimental approaches to inform their bottlenecks. Another way to say all this is there’s inherent coordination headwind when you have deep technical experts in disparate domains trying to solve hard problems together. When everyone gains a just a little more breadth with the help of AI tools, what felt like cavernous gaps between siloed teams requiring heavy handed operational coordination now feels like more fluid collaboration.

My take on the whole "AI cures cancer in dog in Australia". It's a very interesting story, but perhaps not for the reasons that are being noted. In 2007, Freeman Dyson published an essay in The New York Review of Books called “Our Biotech Future.” It contains one of the most memorable predictions about the future of biology I’ve ever read. “I predict that the domestication of biotechnology will dominate our lives during the next fifty years at least as much as the domestication of computers has dominated our lives during the previous fifty years.” Dyson believed biology would eventually follow the trajectory of computing. At first, powerful tools live inside large institutions - universities, government labs, major companies. Over time those tools get cheaper, easier to use, and more widely distributed. Eventually individuals start doing things that once required entire organizations. “Biotechnology will become small and domesticated rather than big and centralized.” He even imagined genome design becoming something almost artistic: “Designing genomes will be a personal thing, a new art form as creative as painting or sculpture.” Dyson's words rang in my mind as I read the "AI cures dog cancer" story. Much of the coverage framed this as an example of AI discovering new science. But that’s not really the interesting part of the story. The scientific pipeline involved here is actually well known. It closely mirrors the workflow used in personalized neoantigen vaccine research that has been under active development for years. The steps are fairly standard: sequence the tumor, identify somatic mutations, predict which mutated peptides might be recognized by the immune system, encode those sequences in an mRNA construct, and deliver them to stimulate an immune response. The biological targets themselves were almost certainly not new discoveries (I have been unable to find out what they are, but mutations in targets like KIT which are common might be involved). Partly therein lies the rub, since the hardest part of drug discovery, whether in humans or dogs, is target validation, the lack of which leads to lack of efficacy - the #1 reason for drug failure. In neoantigen vaccines, the proteins involved are usually ordinary cellular proteins that happen to contain tumor-specific mutations. AlphaFold which was used to map the mutations on to specific protein structures is now a standard part of drug discovery pipelines. The challenge is identifying which mutated peptides might plausibly trigger immunity. What is interesting though is how the pipeline was assembled. Normally, this type of workflow spans multiple domains - genomics, bioinformatics, immunology, and translational medicine - and in institutional settings those pieces are distributed across specialized teams, document sources and legal and technical barriers. Navigating the literature, selecting computational tools, interpreting sequencing results, and designing a candidate mRNA construct is typically a collaborative process. In this case, AI appears to have helped compress that process, pulling together data and tools from different sources. Instead of requiring multiple experts, a motivated individual was able to assemble the workflow with AI acting as a kind of guide through the technical landscape. I’ve seen something similar in my own work while building lead-optimization pipelines in drug discovery. The underlying science hasn’t changed, but the friction involved in assembling the workflow can drop dramatically. Tasks that once required stitching together multiple tools, papers, and areas of expertise can now often be executed much faster with AI helping navigate the terrain; and by faster I mean roughly 100x. That kind of workflow compression is powerful, to say the least. When the cost of navigating technical knowledge drops, more people can realistically assemble sophisticated research pipelines. This story is a great example of what naively seems like a boring quantitative acceleration of the research process. In that sense, therefore, the real novelty here is not the biology but the combination of three things: a non-specialist orchestrating a complex biomedical pipeline, AI acting as a navigational layer across multiple technical domains, and the resulting decentralization of capabilities that were once confined to institutional research environments. But I think the story also points to something deeper, which is a challenge to modern regulatory environments. Modern biomedical innovation does not operate solely according to what is scientifically possible. It is structured by regulatory frameworks - clinical trials, safety oversight, institutional review boards, and regulatory agencies. Those systems exist for important reasons, but they also assume that the development of therapies occurs primarily within large, regulated organizations. When individuals begin assembling pieces of these pipelines outside those institutions, the relationship between technological capability and regulatory oversight starts to shift. The dog in this story sits outside the human regulatory framework. That fact alone made the experiment possible. In other words, the story is not just about technological capability; it is also about how certain forms of experimentation can occur when they bypass the regulatory pathways that normally govern biomedical innovation. One is reminded of another Australian, Barry Marshall, who received a Nobel for demonstrating through self-experimentation that ulcers are caused by bacteria. This raises an interesting question: what happens when the tools for assembling sophisticated biological workflows become widely accessible while the regulatory structures governing them remain institution-centric? That tension may ultimately be the most important implication of this moment. Regulatory frameworks will need to adapt to this kind of citizen science. Seen in this light, the story about the AI-assisted vaccine is less about a breakthrough in cancer therapy and more about a glimpse of the early stages of something Dyson anticipated nearly two decades ago: the domestication of biotechnology. If AI continues to reduce the cognitive overhead required to navigate biological knowledge and assemble complex pipelines, the boundary between professional research and motivated individuals may begin to blur. That shift will require careful thinking about safety, governance, and responsibility. But it also carries an exciting possibility. Dyson imagined a world in which biological design might eventually become something like a creative craft practiced not only by institutions but also by curious individuals experimenting at smaller scales. For a long time that vision felt distant. Now, it feels like we may be seeing the first hints of it.

My long-time best friend since 6th grade (with one of the most exquisite voices I have ever heard) performed as Jeanie in Hair the musical when we were in high school. As a result, I know the soundtrack lyrics like the back of my hand because I saw the performance live a million times. The DTF St. Louis intro features a song from the musical (let the sunshine in), and it’s bringing all the memories back
