I think this hysteria over AI becoming sentient is absolute horse manure. GIGO. AI programs can only simulate sentience. They can get closer and closer to appearing to be sentient, but the idea of a leap to independence is ridiculous. Afraid they'll take over? Hit the circuit breaker! Buh bye!
I don’t think the problem lies with sentience. I can’t envision sentience as separate from love of being. The problem I can see is the possibility that intelligence, not sentience, being manipulated artificially, as everything is, by the human by the human disease of greed that flows out of the neediness created by self hate.
The manipulation of an unaware but intelligent machine directed to a goal by programming the reward it receives as in accordance with sick ego need or even naively conceived positive goals Is more the worry I see.
I think it more likely that the universe we see is perhaps already sentient with us as the maladaptive intelligences attempting to augment our own shallow aims with machines motivated similarly as we are by our own self hate.
