Unpopular opinion: Let us say AI achieves general intelligence levels. We tend to think of current economy, jobs, research as a closed system, but indeed it is a very open system.

Humans want to go to space, start living on other planets, travel beyond solar system, figure out how to live longer and so on. The list is endless. Without AI, these things would take a very long time. I believe AI will accelerate all these things.

Humans are always ambitious. That ambition will push us to use AI more than it's capabilities. The AI will get better at these new things and the cycle repeats. There's so much humans know and so much more that we don't know.

I'm less worried about general intelligence. Rather in more worried about how humans are going to govern themselves. That's going to decide whether we will do great things or end humanity. Over the last 100 years, we start thinking more about "how" to do something rather than the "why". Because "how" is becoming more and more easier. Today it's much more easier and tomorrow even more. So nobody's got the time to ask "why" we are doing something, just "how" to do something. With AI I can do more. That means everyone can do more. That means governments can do so much more. Large scale things in a short period. If those things are wrong or have irreversible consequences, we are screwed.
