AGI is not an IF, but a WHEN.

Everything about a human being happens inside a brain and only a brain. And a brain is just a bunch of cables. It's big and has a complex structure, but it still is only that.

What we call "consciousness" and "free will" derive from this specific system (and from nothing else). They are "side effects" of the specific organization of neurons.

Once we have an artificial entity able to replicate this structure and organization, then it will produce the same effect. Same logic, same cause, same result.

AGI will necessarily demonstrate a form of consciousness (even if most people, due to religious bias but also to the technical difficulty to prove consciousness), will reject the idea. But it will not change the fact that AGI will equal and even surpass human capabilities.
