It's a force multiplier. It can be used for good or bad. I'd rather that we democratize access to these tools - IMO it's better than an alternative where only megacorps have access and do what they like behind closed doors.
What jimrandomh is talking about is not just whether megacorps use AI for good or bad, but what happens if an AI starts doing damage outside the control of anybody. That could happen regardless of democratization if advancement occurs too quickly without thinking about AI safety.
