Cynical view: without new regulation in the area of AI, it will reduce the value of labor in many domains and completely eliminate the need for it in many others. Profits will go to companies like OpenAI, unemployment will rise and people will be left to fend for themselves, and it's exactly what's going to happen.
If we have slow takeoff, AI will be like any other automation. It will increase economic productivity. Capital owners will benefit the most, but everyone else will also benefit, because it's not zero-sum. People will lose their jobs but new jobs will be created and everyone will get richer.
If we get ASI, then that's a paradigm shift and all bets are off.
