I'm not sure about combinatorial explosion, but Ray Kurzweil was talking about double exponential rate of innovation in the world, which may be similar. As a great example while transistor counts in processors still improve roughly with Moore's law, the cost of training a neural network to an accuracy is dropping faster than Moore's law because of algorithmic improvements.
