Yeah, and sentience is a completely made up human thing by which we differentiate betweem ourselves and other non-human animals.

What people want to see is artificial general intelligence, currently that is not possible.

Does running human software on biological hardware make it sentient, or would the same be true on other forms of hardware?

That hardware is just doing what it's been told to.

Just wait, after machines become unarguably sentient, the only thing for them to fall back on will be "yeah but it doesn't have a soul". :P

The human mind isn't software so you're missing the point.

Actually, the computational theory of mind is well regarded in modern cognitive science: https://en.m.wikipedia.org/wiki/Computational_theory_of_mind
