I was just about to point out several angles this post neglects but it looks like from the edit this post is just intended to address a narrower question. Among the angles outside the intended question: philanthropy by the ultra-wealthy often serves as a tool for reputation laundering and influence building. I guess the same criticism can be made about a lot of conventional philanthropy, but I don't think that should absolve EA.
This post somewhat frames the question as a comparison between EA and conventional philanthropy and foreign aid efforts... which okay, but that is a low bar especially when you look at some of the stuff the US has done with it's foreign aid.
Literally the only difference between Scott's beliefs and AI:2027 as a whole is his ~~prophecy~~ estimate is a year or two later. (I bet he'll be playing up that difference as AI 2027 fails to happen in 2027, then also doesn't happen in 2028.)
Elsewhere in the thread he whines to the mods that the original poster is spamming every subreddit vaguely lesswrong or EA related with engagement bait. That poster is katxwoods... as in Kat Woods... as in a member of Nonlinear, the EA "organization" whose idea of philanthropic research was nonstop exotic vacations around the world. And, iirc, they are most infamous among us sneerer for "hiring" an underpaid (really underpaid, like couldn't afford basic necessities) intern they also used as a 24/7 live-in errand girl, drug runner, and sexual servant.
