Incredible! Excited to see the peer reviewed version.

2/ TL/DR: We found neural activity across both inferotemporal and prefrontal cortex alternates between a conscious mode and an unconscious mode ~ 15 times every second.

A Scientist Says There’s a Key to Being Conscious—and AI Doesn’t Have It

Consciousness may not come from intelligence at all—but from a struggle machines will never know.

Consciousness Evolved to Referee the Body's Competing Survival Drives - Daily Neuron

Hunger says go, fear says stay, and something in you has to break the tie. One theory argues that tiebreaker is where feeling itself comes from.

Well, I’d add one more with myself, as one with a PhD in biology and another PhD in AI and now working in both, to make n=2. Generating a hypothetical genome blueprint of a virus from LLM versus generating a true virus are completely different things. It is either an intentional attention-harnessing lie or true ignorance. The material, the manufacturing, and actual biological viability of paper-to-physical transformation is the gap you need to close. Like drawing a design of a chip or A-bomb, versus actually make one. You have, and can add more checkpoints and guardrails all over this long chain of paper to physical transformation. Fear mongering is not well founded, and mostly emotional manipulation.

I must be among an extremely small group of people (n=1?) that have both 1) trained a frontier LLM and 2) designed and synthesized custom viruses in a lab with my own two hands. And I think that the takes on AI killing us all by creating dangerous viruses is total bogus.

This was personally important, as it was in part a tribute to my late friend and mentor Dan Dennett, who deeply informed my thinking on this topic.

An old and worthy insight from the Nobel laureate and originator of cognitive psychology and artificial intelligence, Herb Simon: Don't spend 15 minutes figuring out a shortcut that will save you 10 minutes. Information-gathering and decision-making themselves have costs, so "satisfice" rather than seeking to optimize. This op-ed by David Epstein draws out implications for life decisions. nytimes.com/2026/05/12/opini…

Human brains have been shrinking since prehistoric times, some studies suggest. Whether this is true and why it has happened are debated. livescience.com/archaeology/…

If humans are getting smarter, why are our brains shrinking?
