We had more than half a century of for example sci-fi literature describing that future, and over all those decades nobody was able to come up with even half-good plausible/feasible idea of how to deal with that. That suggests that it is outside of human intelligence capabilities to stop that snowball. Personally, i read a lot of sci-fi in my youth and i'm prepared to accept such my/our fate, even happily working where i can to speed it up (the faster the changes, the faster the human evolution (or at least adaptation) and what can be more exciting than that).

Current humans can't even deal with very simple and obvious issue of global warming. Thus it seems very unreasonable to expect any effective dealing with significantly more complex issues. And thus if not evolution then at least very accelerated adaptation is in order.
