I have the impression a lot depends on people's past reading and knowledge of what's going on. If you've read the likes of Kurzweil, Moravec, maybe Turing, you're probably going to treat AGI/ASI as inevitable. For people who haven't they just see these chatbots and the like and think those won't change things much.

It's maybe a bit like the early days of covid when the likes of Trump were saying it's nothing, it'll be over by the spring while people who understood virology could see that a bigger thing was on the way.

These people's theories (except Turing) are highly speculative predictions about the future. They could be right but they are not analogous to the predictions we get out of epidemiology where we have had a lot of examples to study. What they are doing is not science and it is way more reasonable to doubt them.
