Edit>> Though if Baidu is investing in AI like all the rest, then maybe they just think they’ll be immune — in which case I’m sad again that I haven’t yet come across a CEO who calls bullshit on this nonsense.

They may just have kept their AI investments responsible—that is, not put more money into it than they can afford to lose. Keep in mind, Baidu is the Chinese equivalent of Google. They have a large, diversified business with many income streams. I expect they’ll still be around after the bubble bursts.
