via LessWrong AI [4] — There's an adage from programming in C++ which goes something like "Yes, you write C, but you imagine the machine code as you do." I assumed this was bullshit, that nobody actually does this. Am I supposed to imagine writing the machine code, and then…

via LessWrong AI [4] — Before I had a baby I was pretty agnostic about the idea of daycare. I could imagine various pros and cons but I didn’t have a strong overall opinion. Then I started mentioning the idea to various people. Every parent I spoke to brought up a consideration…

via LessWrong AI [3] — Last year, my colleagues on MIRI’s Technical Governance Team proposed an international agreement to halt risky development of superhuman artificial intelligence until it can be done safely. The agreement would require all clusters of AI chips with more…

via LessWrong AI [5] — Even if we solve the AI alignment problem, we still face post-alignment problems, which are all the other existential problems [1] that AI may bring. People have identified various imposing problems that we may need to solve before developing ASI. An…

via LessWrong AI [6] — But I had to get 500 words out! I think the 2013 conversation is interesting reading as a piece of history, separate from the top-level question, and recommend reading that.I think many people have a relationship with Anthropic that is premised on a false…
