People are far better at subconsciously processing the consequences of something than they appreciate, and the consequences of the AI wave being real are so insane people just clam up and back track to "it's obviously not happening".
If people actually did appreciate it the economy would collapse immediately long before we've adequately "replaced" it, so there is something to be said for temporary denial until people working on the actual consequences have got something semi viable to deal with them in place.

You will need to explain that one. Becauase if economy colapses before the singularity, there will be no singularity.
There will be no datacenters, no ai, none of that super expensive stuff dependent on debt and disposable money.
