Most coverage of the firing of Sam Altman from OpenAI is treating it as a corporate board firing a high-performing CEO at the peak of their success. The reaction is shock and disbelief. But this misunderstands the nature of the board and their legal duties. 1/n.

Because the space between us is stretching, the current distance to the galaxy is 15 times larger than it was when the light began its journey towards us. That's how it can be 34 billion light years away when the light has only travelled for 13.5 billion years. 4/.

@Austen The board fired him, and he worked with one of the world's richest companies and the employees of the for-profit (who have large financial incentives) to overturn that. He is supposed to be accountable to the nonprofit board. That is what he told us.

I've been very impressed by how quickly the COVID-19 vaccine research at Oxford has progressed. They are now opening phase II and III trials, looking for 10,000 participants. If you live in the UK you may be eligible to take part. I applied tonight.

Very exciting to see my work profiled in the @NewYorker. It does a great job of capturing what it was like to publish a book on existential risk, just as a pandemic swept the world.

New paper: The Lindy Effect. One book has been in print for 3 years; another for 300. Which should we expect to go out of print first? 🧵.

Stuart Russell was one of the first to point out that AI systems of the future could read all of the books about ethics and know as much about the study of ethics as anyone (with the next challenge being to make them *care*). So I wondered: what does GPT-4 know about ethics?.1/n.
