There are sizeable camps for both those opinions.

I mostly agree, except for the Messiah part.

I think the optimistic excited people are thinking more 'What a time to be alive' than 'All praise be, for they have come'

Which is not to say there won't be people deifying AI, I just don't think there are many of those yet.

The cynical side of me thinks it will happen, but right now I feel like most of those who seem susceptible to that kind of thinking are tending towards the Butlearian.
