Gnrf he actually does play the engines moves check any of his solid games with stockfish or Komodo or Houdini. Next make sure you say something correct instead of embarrassing yourself. It is actually true.
I have checked some games on Kingscrusher's channel. He uses Komodo, Rybka, and Fritz. Carlsen makes engine moves in positions where he has an advantage and there is only 10 moves to consider, yes.
But not in a way as you say.
Even lichess's browser version of Stockfish with only 256 mb ram allocated points out his errors.
I do and can believe that a human brain uses 20 watts, that's not what I disagree with. What I say is that there is no clear number as to how many of those 20 watts you spend solely on chess. That number, we will never know, because there are a million variables and a million 'background apps' in our brains that also come into play. And since we can theoretically put a number of how much a computer processor actually uses, it's pointless to compare the two until we can do the same with a brain as well.
