> I feel like I've been playing against it a lot in chess.com, with the tremendous amount of cheating that is going on online, every 1 out of 6 or 7 games is an engine user

This statement seems a bit funny because in order to have a good idea that they cheated, you would have also had to been analyzing the game with the chess engine.

Regardless, unless you truly an amazingly player, nearly any chess engine made in the last 15 years will destroy you and incremental improvements on stockfish have absolutely not effect on that.
