Voting behavior in the 2020 election is strongly correlated with per capita Covid-19 case prevalence, with red states leading total case counts (even California, which has the largest total case count is a distant 36th in terms of spread).

Great article by Ezra Klein highlighting the importance of transitioning from animals to more efficient means of converting plants to the foods we love most. nytimes.com/2021/12/16/opi…

Republicans are getting very upset people keep retweeting this ad so I figured I would post for any of you who haven’t seen it yet and then I am going to retweet myself tonight.

This interesting idea is being popularized especially by people in the crypto + AI intersection (e.g., Worldcoin’s mission, posts from Balaji Srinivasan, Vitalik Buterin and some xAI-adjacent thinkers) who argue that AI and crypto are symbiotic. AI needs crypto’s trust layer

The scientists who spend decades developing intuition about protein folding, materials behavior, or drug interactions - they should be partners in the AI revolution, not inputs to it. Right now there's no infrastructure for that partnership. We can build it.

Interesting tension in AI right now: the labs need expert knowledge to get better at hard problems, but experts have no real incentive to contribute. The current model is basically "give us your expertise for free and maybe we'll compete with you later." Doesn't seem stable.

My writing today in the The San Francisco Standard: Too many Silicon Valley leaders have divested themselves of the responsibility to speak out against the Trump administration. We can’t shrink away and hope the crisis fades. It’s time for all of us in tech to do and say more.

I’ve been encouraged in recent days that more Silicon Valley leaders (Paul Graham & Vinod Khosla, just to name a few) have spoken out to condemn the Minneapolis killings and the policy choices that led to them. It’s a good start to something America needs much more of right now.

We measured what happens when AI compresses your conversation to fit the context window: At 5x compression, 75% of the specific facts you told it are gone. At 10x, all of them. The model doesn't flag any of it. It just keeps working with full confidence on wrong assumptions.
