You seem to have this optimistic view that humanity is invincible against any threat but itself
I didn't say that. You're making assumptions. However, I don't take AGI as a serious risk, not directly anyway. AGI is a big question mark at this time and hardly comparable to a giant comet or pandemic, of which we have experience or solid scientific evidence. Could it be a threat? Yeah. Do I personally think so? No. Our reaction to and exploitation of will likely do far more harm than any direct action by an AGI.
