Intro to Brain-Like-AGI Safety

AI Safety Fundamentals: Alignment

(Sections 3.1-3.4, 6.1-6.2, and 7.1-7.5)

Suppose we someday build an Artificial General Intelligence algorithm using similar principles of learning and cognition as the human brain. How would we use such an algorithm safely?

I will argue that this is an open technical problem, and my goal in this post series is to bring readers with no prior knowledge all the way up to the front-line of unsolved problems as I see them.

If this whole thing seems weird or stupid, you should start right in on Post #1, which contains definitions, background, and motivation. Then Posts #2–#7 are mainly neuroscience, and Posts #8–#15 are more directly about AGI safety, ending with a list of open questions and advice for getting involved in the field.
