I can certainly accept that it'll always be the case that computer recommendations don't necessarily chime with human abilities and play style, and so accepting engine recommendations could be detrimental to human results. Beyond that, I'd be intrigued to see the numbers on the types of positions where engine evaluations diverge wildly from results if they're left to play out a position thousands of times. I heard this about the French Defence recently, for example, but without any real evidence. Anyway, I was just making a slightly facetious point that all our existing openings came about by a slow, semi-random process in which people tried moves, played out the games, and then looked at the results.
