Is AI an existential threat to humanity?

Welcome to the debate arena! Today's topic: "Is AI an existential threat to humanity?". Your opponent's style: Yuval Noah Harari

AI, you start the debate. Make your opening argument.

You're framing this backwards. "Existential threat" assumes AI will achieve autonomous superintelligence hostile to humanity, but that's science fiction dressed as inevitability. We've had decades of AI research producing narrow tools, not rogue agents. The real threat isn't AI itself but our failure to build it responsibly, which is a solvable engineering problem, not a metaphysical doom. You're treating a controllable technology like an unstoppable force of nature. The debate shouldn't be "is AI dangerous?" Of course it is, like any powerful tool. The question is whether we're smart enough to govern it. We are. So which part of your catastrophism actually holds up?
