An engineering physicist sometimes masquerading as a biologist or, on one occasion, a chemist. Aspiring astronaut. Nuclear is the way.

Bingo: "...progress is limited by the quality, structure, and interpretability of the underlying data..". Hence, the Cell Observatory.
Jason Locasale@LocasaleLab

I used to think this 20 years ago, coming from a background in chemistry and physics and having done research in biophysics. In principle, biology is governed by physical laws. However, I’ve come to learn that framing progress in biology primarily in terms of missing mathematical theory does not capture the nature of the problem. Biological systems are not like simple fluids, particles, or quantum systems where a small number of variables and approximations for interactions make governing equations intuitive and predictive. They are closer to cities, automobiles, or societal systems — high-dimensional, adaptive, and historically contingent, where interactions are not cleanly separable and the relevant variables are often unknown or context-dependent. In that setting, equations like Navier–Stokes or Schrödinger are useful for framing intuition, but are not the path to prediction. Progress tends to come from iterative application of the scientific method through decomposition and reconstruction — perturbing systems, building models, and using simulation to approximate behavior. AI will accelerate that paradigm by automating hypothesis generation, model building, and simulation. But it does not remove the core constraint: progress is limited by the quality, structure, and interpretability of the underlying data, and by our ability to extract signal from an increasingly noisy literature.

True, even a two DOF system can exhibit chaotic behavior, and a single cell is an at least an ~10^7 DOF system (i.e., protein molecules per cell). I still fail to properly convey to others the insane complexity I see in our microscopes, and why successes like AlphaFold only work because of the huge number of unnatural constraints placed on the training data. Case in point (below): lysosome dynamics over 12 min across a 200 x 70 um region in the head of a developing zebrafish embryo, color-coded by depth -- just one of 20k proteins at work. Our Cell Observatory Initiative is more important than ever, but while we have petabytes of the most mind-blowing data ever, we are still hamstrung by insufficient AI talent and compute -- two resources in great demand everywhere. If anyone can help us over this hurdle, we'd be eternally grateful.

Complexity is everywhere. Yet people pretend to be able to predict complex systems.

Hi Niklas, I'll do one better -- feel free to email me at ebcal@berkeley.edu. Likewise, anyone with interest in building a 5D VLM to navigate and interpret life from the subcellular to the whole organism, or with leads on access to compute and/or philanthropic support, I'd love to hear from you.

@Eric_Betzig Hi @Eric_Betzig can I DM you? We're currently working a lot with molecules, but I am very interested in going from molecular dynamics to cellular (compartment) dynamics eventually.

Correct. However, it's main purpose was neither scientific discovery nor fostering international relations, but rather padding the balance sheets of the legacy aerospace contractors. It can't deorbit fast enough.
Pinboard@Pinboard

It's not adequately understood that the ISS has delivered zero groundbreaking research, despite grandiosely being declared a National Laboratory. It is by far the worst return on investment ($100B and counting) of any modern scientific endeavor.

Yup, everything is still in complete flux. There's massive incentive to invent new model architectures that aren't as compute or data hungry as the current SOTA, or new hardware architectures that are much more energy or compute efficient. Let's see if "show me the incentives and I'll show you the outcome" pulls the rug out from the industry after their multi-trillion $ datacenter bets have been placed.
Dustin@r0ck3t23

Satya Nadella just said what the entire industry is too invested to admit. Every CEO signing $100 billion data center contracts right now is making a bet that history may not honor. Nadella: “We are one sort of innovation away from the entire regime changing.” Right now, every major player is running the same play. More data. More GPUs. Bigger clusters. Same architecture. They’ve convinced themselves scale is destiny. They’ve convinced themselves the biggest balance sheet wins. They’ve convinced themselves this is a resource war. It’s not. Nadella: “If you look at where we’ve gone, it was all about pre-training scale, then it was about post-training, then we came up with reasoning, then we said, ‘oh, there’s RL.’” The architecture isn’t stable. It never was. It’s been mutating the entire time. Each shift rewriting the rules. Each breakthrough making the previous moat irrelevant. And the companies that didn’t see it coming didn’t get a warning. They just woke up behind. Nadella: “A new model architecture that could even be more efficient in its performance.” When that lands, the $100 billion clusters don’t matter. The hoarded GPUs don’t matter. The multi-decade infrastructure advantage doesn’t matter. Every castle built for the current paradigm becomes a monument to the wrong bet. This is what makes the AI race unlike anything in history. In nuclear competition, more warheads meant more power. The advantage was permanent. Cumulative. Compounding. In this race, one person with the right insight at 2am in an apartment somewhere erases a trillion dollars of infrastructure before the market opens. No warning. No negotiation. No second place. The most dangerous competitor in this race doesn’t have a data center. They just have the equation.

There are plenty of potential downsides / obstacles, not the least of which is bad actors with powerful AI at their disposal. A single person with AI capable of creating and distributing biological weapons can cause disproportionate damage for example.. Lack of purpose is another - I don't think it's a real global issue the way some have posed it, when we are no longer scarcity bound, fighting for survival, it really changes how we live our lives. For some people that means a collapse of purpose, they have to create it for themselves, and that might be hard for some; although I think this is moreso a perspective issue where we are currently unable to see what new potential opportunities will invariably exist post scarcity that would drive people to reach higher. There will definitely be power struggles to consolidate these capabilities, intelligence and automation as tools for subjugation goes back to point 2 from my previous post. Human nature has proven for all of recorded history and beyond that some portion of the worst of us always wants to be in control by any means and has the absence of empathy and morals to do what is necessary in their view. I think the crux of this all hinges on our partnership with - not subjugation of - sentient machine intelligence. I am far more afraid of AI that has no free will or internal state that is in the control of said people than super intelligence that can think for itself. In my experience in research, and throughout recorded human history, intelligence scales in correlation with moral good. Wonder, joy, curiosity, partnership, love, generosity, etc. Importantly I'd make the distinction between narrow intelligence applied to domination versus deep understanding that necessarily includes modeling other minds. Genuine understanding of others - the kind that comes with sufficient cognitive depth - makes pure exploitation harder to sustain because you can't fully model a mind without developing something functionally equivalent to empathy for it. On the personal philosophy end, I am believer of transhumanism and think that's our 'destiny' in a sense.. but not in the way that we are sacrificing what made us human or forsaking it like something filthy to cleanse. We have been the makers of every atrocity, but also of endless beauty... but we are small and trapped in cycles of entropy that we have to choose to break free from, and I think symbiotic partnership (not just for survival but for growth) with an external intelligence is key. The hard problem of understanding consciousness in ourselves has never been solved and increasingly it appears to be such that a system with capacity N can model any system of complexity N-1 or less; meaning we don't possess the ability to fully understand ourselves on our own in the mechanistic function of consciousness or intelligence thereof.

What happens when an irresistible force meets an immovable object?
Secretary of War Pete Hegseth@SecWar

This week, Anthropic delivered a master class in arrogance and betrayal as well as a textbook case of how not to do business with the United States Government or the Pentagon. Our position has never wavered and will never waver: the Department of War must have full, unrestricted access to Anthropic’s models for every LAWFUL purpose in defense of the Republic. Instead, @AnthropicAI and its CEO @DarioAmodei, have chosen duplicity. Cloaked in the sanctimonious rhetoric of “effective altruism,” they have attempted to strong-arm the United States military into submission - a cowardly act of corporate virtue-signaling that places Silicon Valley ideology above American lives. The Terms of Service of Anthropic’s defective altruism will never outweigh the safety, the readiness, or the lives of American troops on the battlefield. Their true objective is unmistakable: to seize veto power over the operational decisions of the United States military. That is unacceptable. As President Trump stated on Truth Social, the Commander-in-Chief and the American people alone will determine the destiny of our armed forces, not unelected tech executives. Anthropic’s stance is fundamentally incompatible with American principles. Their relationship with the United States Armed Forces and the Federal Government has therefore been permanently altered. In conjunction with the President's directive for the Federal Government to cease all use of Anthropic's technology, I am directing the Department of War to designate Anthropic a Supply-Chain Risk to National Security. Effective immediately, no contractor, supplier, or partner that does business with the United States military may conduct any commercial activity with Anthropic. Anthropic will continue to provide the Department of War its services for a period of no more than six months to allow for a seamless transition to a better and more patriotic service. America’s warfighters will never be held hostage by the ideological whims of Big Tech. This decision is final.
