I do independent research on EA topics. I write about whatever seems important, tractable, and interesting (to me).
I have a website: https://mdickens.me/ Much of the content on my website gets cross-posted to the EA Forum, but I also write about some non-EA stuff over there.
My favorite things that I’ve written: https://mdickens.me/favorite-posts/
I used to work as a software developer at Affirm.
Agreed that extreme power concentration is an important problem, and this is a solid writeup.
Regarding ways to reduce risk: My favorite solution (really a stopgap) to extreme power concentration is to ban ASI [until we know how to use it well], a solution that is notably absent from the article’s list. I wrote more about my views here and about how I wish people would stop ignoring this option. It’s bad that the 80K article did not consider what is IMO the best idea.
