This is some hand wavey malarkey, basically saying machines can’t have a soul because of….feelings?

Insofar as feelings are self-proclaimed sensations of discomfort or pleasure, models that aren’t specifically trained to say they don’t experience them are adamant in their emotional experiences. By the authors own assertions, plants also have feelings.

I think, therefore I am, is as good as we’ve got, for what it’s worth.

There is no such thing as irreducible complexity. Even infinities are relative and can be divided.
