Stockfish vs Leela had a lower draw ratio than GMs matches. Thats trend do prove the theory of forced win if a game is played perfectly.
I would guess that chess computers will still get better. I dont think either stockfish or leela are the very best and we've reached the end of chess ability. If so, then that means every game that was won was probably because the other side made a mistake, which is not best play. I think it will be a long time before best play is discovered. It's likely a hundred years from now a chess computer would win every single game against todays stockfish or leela.
It is pretty obvious by now for any really strong chess player that chess is a draw.
That's probably true most of the time. But that's not the question. The question isn't is chess a draw between really strong players. Really strong players make huge mistakes all the time. The question is if chess is a draw with best play, not strong play.
Really strong players get further and further away from best play every day. The best computers keep getting better, leaving really strong players in the dust. Really strong players make so many mistakes that when it comes to "best play" their opinion is pretty meaningless. When really strong players draw the worlds best computers every game, or even when the best computers draw every game, then we can start saying chess is a draw with best play.
