From reading the text of the article, and the direct quotes, I'm also unclear on why they booed him.

My guess is because of what he's done, or at least perceived to have done, in the area of AI. Because what he said (at least to me) didn't seem boo-worthy, but in the context of who is saying it, I can see it.

Put another way, if someone that the audience liked said the same things, its not clear the person would get booed.
