I don't think it is a fair comparison. We have the ability to build somewhat working strategy from known parts, and then we still need thousands of hours (or man-years in the case of Go) to improve it and to teach the brain to do some parts without conscious attention. Alpha Zero, OpenAI Five and others build strategy (mostly) from scratch. I have a feeling that it is not possible to reduce algorithmic complexity of finding optimal solutions in most of the intellectual tasks (those that are in NP complexity class and above). Most likely it is a trade-off. Quickly cobble up suboptimal strategy / build better strategy from scratch avoiding all time-saving benefits of using known parts, and avoiding all the pitfalls of not reevaluating utility of those parts in the current situation. AIs surely will need to use all the spectrum to compete with humans.
