The low-hanging fruit was picked way back. However, these small, incremental changes are going to pile up and amount to what ends up being a qualitative change. Also: I'd not fear a new dark age. Chinese or other East-Asians are bound to get to the business of modifying embryos for higher mathematical intelligence before 2060. That's going to induce quite a jolt for the sciences, even if 3/4 of those kids end up doing something else.
