Ask HN: If AGI is achieved – what happens next?

This week I learned the term AGI. I found a video online speculating why Sam Altman may be looking to raise trillions $.

If AGI is really achieved, what do you think would happen next. How would the stock market react, winners, losers?

What would happen with the value of money and human society in general.

Interesting to hear what people think, it can't be all doom and gloom. How would we control this thing?
