Earlier quoted context omitted.
Human chess players are still incredibly valuable because we want to see what humans are capable of. For the same reason athletes are valuable even though a car can outrun them. With mathematicians, and others working in intelligence-intensive tasks (most of us here probably), I’m not sure what the value would be post-AGI.
Bluntly speaking, I think it is going to be the journey that matters; to work with mathematics is to work on yourself and a way to explore your creativity.
To be clear I don’t think AI is bad, and even if it is I’m pretty damn sure it’s not avoidable. But we’re in for drastic changes and we should start getting used to it.
