I have had this same thought, and I think it would make a good premise for a fictional world. In my imagination, I call it "the Phoenix Project."

The problem, of course, is that humanity is not going to survive long enough for this goal to be relevant. The climate crisis will likely exterminate the majority of aerobic life by 2100. If anybody survives, it will be a handful of billionaires and dictators, and those dummies are frankly not capable of perpetuating a functional species.

All humans and all human descendants will be dead before 2200.
