I largely agree, and this is actually something I've been thinking for a while. The problem was never the algorithm; it's the game the algorithm is trying to solve. It's not clear to me what extent we can push this to aside from math, coding. Robotics should be ripe for this, though.
Unfortunately the feedback loop for robotics is many many orders of magnitude slower than math / coding problems. And when you get to artificial environments, you are learning artificial dynamics -- same limitations as the benchmarks.
