Hogwash. First, the “mind” and consciousness are products of the combination of the physical brain and the soul. I would say that the soul is the source of consciousness and thought, and the brain is the interface between the soul and the physical world. Refusal to consider the spiritual element of “mind” is why no matter how sophisticated computers get, they will never approach the reasoning capability of humans, will certainly never come anywhere near achieving “consciousness”, and will always be subject to making unexpectedly dumb mistakes.
Computers will continue to get much better at performing rote tasks, and will improve in appearing to mimic human behavior, but underneath it all they will never be anything more than dumb machines, carrying out programs that humans have inserted into them. Think far more Siri rather than HAL9000.
When these AI "zombies" are perfected so as to perfectly ape human behavior then the scientists will instruct humanity to fade away to allow these superior beings to take our place.
The answer to the Fermi Paradox could be that once a civilization becomes advanced enough to create AI zombies they allow themselves to be replaced hoping the AI zombies will travel and explore the Universe.
Only the AI zombies with no real consciousness or curiosity end up just staying put on whatever planet they were created on, or power themselves down waiting for further instructions that never arrive.
