I tend to agree, but it certainly seems like Sam Altman and Paul Graham don't. I'm reasonably confident that they would do more if they thought Trump being elected was more likely.

Also, you paint a terrifying picture of what happens next - as you (IMO correctly) point out, Trump will not just disappear, but will probably be setting up the next election. Which isn't even the worst case - the worst case is a serious and ongoing Trump challenge to Clinton's election.
