I agree. I have the same reactions to these guys as I did to religious zealots when I was a teenager; and later to "transhumanism". Alarm, disbelief, hostility.

There is a new secular religion underneath this.

"Uploading consciousness", "Aren't we all just data systems?", "We've built a neural network with as many (meaningless) neurones as the brain!"

It's the same disgust and denial at being biological animals that all religions foster.

Thankfully here, I think, the religion has predictions. It predicts a self-driving car, a "fourth industrial revolution", and so on. When these fail to materialise, some sanity will return.

(Of course they have already failed, the question is when in the next 5-10yrs people will realise.)
