Basically this: "Eliezer Yudkowsky writes and pretends he's an AI researcher but probably hasn't written so much as an Eliza bot."
While the Eliezer S. Yudkowsky site has lots of divulgation articles and his work on rationality is of indisputable value, I find myself at a loss when I want to respond to this. Which frustrates me very much.
So, to avoid this sort of situation in the future, I have to ask: What did the man, Eliezer S. Yudkowsky, actually accomplish in his own field?
Please don't downvote the hell out of me, I'm just trying to create a future reference for this sort of annoyance.
Uh huh - well that seems kind-of appropriate for a resource-limited agent. The more of the universe you consider, the harder that becomes - so the more powerful the agent has to be to be able to do it.
Yudkowsky's idea has agents hunting through all spacetime for decision processes which are correlated with theirs - which is enormously-more expensive - and seems much less likely to lead to any decisions actually being made in real time. The DBDT version of that would be to put the "critical point" at the beginning of time.
However, a means of cutting down the work required to make a decision seems to be an interesting and potentially-useful idea to me. If an agent can ignore much of the universe when making a decision, it is interesting to be aware of that - and indeed necessary if we want to build a practical system.
