The problem with that statement is that it doesn't say anything about why AI will take over pretty much everything.

The actual answer to that is that AI is not limited by a biological substrate and can thus:

1. Harness (close to) the speed of light for internal signals; Biology is limited to about 200m/s, 6 orders of magnitude less. AI has no such limitations.

2. Scale very easily. Human brains are limited in how big they can get due to silly things such as the width of the birth canal and being on top of a (bipedal) body that uses organic mass to inefficiently generate power. Scaling a human brain beyond its current size and the ~20 watts it draws is an incredibly hard engineering challenge. For AI scaling is trivial by comparison.

I'm not saying it's going to be LLMs, but longterm we can say that the intelligent entities that will surpass us will not have the same biological and physical limitations as we do. That means they very, very probably have to be 'artificial' and thus, that AI taking over everything is 'inevitable'.
