@joe seems pretty clear to me.
-"AI" isn't inevitable
-people who claim otherwise are mostly doing marketing for products in which they're invested
-experts on "AI" should include more than those employed by the companies trying to make a profit off it
Yudkowsky was not a non sequitur; you were asked which experts you consult, you then refused to name any, so your interlocutor tried speculating about who might qualify for you.
Hope this helps, Joe!
