My impression was that periodically there is a leap in the strength of one engine someone is working on (e.g. AlphaZero), and then it outperforms other engines, say in 100 game matches, at least for a while, until the next such cycle begins.
edit: Chess.com is quoted by Google as saying AlphaZero lost 8 games to a version of Stockfish in a recent match, out of 1000 games, causing the loss of the match. Not many decisive results this time around, but wins are still possible at such a lofty level 'at the top' as we have right now, given enough games are played.
edit2: I haven't kept track of the progress quantum computing has been making, but that could lead to stronger engines and perhaps even open the door to solving chess.
