The old question right? Does a simulated (or rather emulated) brain actually think and feel? Or does the computer just output what it would be if it was alive?

I think before I am, but I can’t prove that I’m self aware and not just “pretending” to do so. But because you are a human being like me, I understand that you do too. But that assumption is broken when you are not a physical organism but software running on a computer.
