No, that's not correct.
I did not say it was unrelated to the thread at all. I said it had nothing to do with faster hardware. Faster hardware was one subtopic in this thread that may or may not be regarded as related to the game, but clearly has been agreed to be related to the game because no one ever raised objections to it being discussed at length here. (I've already said my bit on faster hardware. Even if someone here could afford faster hardware, millions of chess-lovers in the world cannot.)
I also said the subject discussed was not specifically about the middlegame (or the endgame, or the opening). It applies just as well to all phases of the game, or at least we don't have reasons to believe it doesn't.
Faster hardware was just one of several subtopics in this thread (and not the one I think is most interesting). Another subtopic is centaurs. I don't think faster hardware affects centaur play, because I assume a centaur with faster hardware will still use roughly the same method. Why would a centaur throw out the method he likes just because he has faster hardware?
