I agree we aren't the same thing, but I would be curious for you to explain how you know with certainty why we don't share enough that we can rule out thinking / feeling / ... as things a model conceptually could do.
Stop anthropomorphizing these models. I understand it, we only have simple monkey brains to reason with and we can't help ourselves but draw comparisons to other things we see in nature. But these things are not alive.
And like I'm sure I'd agree depending on the definition of "alive" but then I'm also sure I would disagree depending on other definitions of "alive".

Or so we currently think. I think this is pretty new science.
Evidence?
