The “principle of indifference” is often presented as an intuitively obvious motivation for specifying “non-informative” prior models. Unfortunately that intuition quickly falls apart in many common applications.  A long thread about applied probability theory!

I'm running an experiment, and holding some public office hours (inspired by Kyunghyun Cho doing something similar). Talk with me about anything! Ask for advice on your research or startup or career or I suppose personal life, brainstorm new research ideas, complain about mistakes I've made, ...

Levels of AGI: Operationalizing Progress on the Path to AGI Levels of Autonomous Driving are extremely useful, for communicating capabilities, setting regulation, and defining goals in self driving. We propose analogous Levels of *AGI*. (ChatGPT is a Level 1 "Emerging" AGI)

These Levels of AGI provide a rough framework to quantify the performance, generality, and autonomy of AGI models and their precursors. We hope they help compare models, assess risk, and measure progress along the path to AGI. (AlphaGo is a Level 4 "Virtuouso" Narrow AI)

A theme is that we should worry about a *diversity* of risks. If we recognize e.g. only specific present harms, or only AGI misalignment risk, we will find our efforts overwhelmed by other types of AI-enabled disruption, and we won't be able to fix the problem we care about.
