The claim is that “computers can be sentient”. That is a strong claim and requires equally strong evidence. I’ve found the arguments in support of it lackluster and reductionist for reasons I’ve outlined in other comments. In fact, I find the idea that if we compute hard enough we get sentience borders on a religious belief in extra-physical properties being bestowed upon physical objects once they pass a certain threshold.

There are people who argue that everything is conscious, even rocks, because everything is ultimately a mechanical process. The base argument is the same, but I have a feeling that most people here would suddenly disagree with them for some reason. Is it “creationism” to find such a hypothesis absurd, or is it vulgar materialism to think it’s correct? You seem to take offense at being called “reductionist” despite engaging in a textbook case of reductionism.

This doesn’t mean you’re wrong, or that the rock-consciousness people are wrong, it’s just an observation. Any meaningful debate about sentience right now is going to be philosophical. If you want to be scientific the answer is “I don’t know”. I don’t pretend to equate philosophy with science.
