“But I think maybe the cruxiest bits are (a) I think export controls seem great in Plan B/C worlds, which seem much likelier than Plan A worlds, and (b) I think unilaterally easing export controls is unlikely to substantially affect the likelihood of Plan A happening (all else equal). It seems like you disagree with both, or at least with (b)?”
Yep, this is pretty close to my views. I do disagree with (b), since I am afraid that controls might poison the well for future Plan A negotiations. As for (a), I don’t get how controls help with Plan C, and I don’t think Plan B/C worlds are much more likely than Plan A, as of now. But I do agree with you that controls help with Plan B, so if you see it as the main hope, I understand why you are supporting them.
(btw. how does one do a proper blockqoute here?)
I am late to this but anyway I’d like to point out that main and huge dowside of export controls is imho that they are poisoning the atmosphere for international cooperation on AI (also on other things), for reasons I tried to explain here: alesziegler’s Quick takes — EA Forum
