- It requires a considerable amount of computation.
- Most people want to solve a particular problem. Neuroevolution might get you to a creative solution but could lead you astray before it puts you on the right path.
- Other AI, like reinforcement learning, can lead to short-terms gains, but will eventually get stuck in a rut. Random exploration in the steppingstone principle can beat the best algorithms.
- Open-ended exploration might lead to human-level intelligence via paths we would never have anticipated.
