AI will solve chess in the near future, that's for sure
Nope.
Yes it will, but stay entitled to your opinion, I will stay entitled to mine.
You are definitely entitled to your opinion, it's just not going to pan out for you.
It's not going to pan out for you, too. I believe in the "impossible" and you seem like you don't.
I know the various directions AI is currently heading, and it's not looking good for solving chess anytime before our sun becomes a red giant. What is your belief in AI's quantum leap based on? Even storing the calculations along the way would take more matter than exists in our solar system, so that's maybe the first hurdle to jump over for you.
Yes and I clarified that in my other post, a 5000 rating may be impossible for that reason.
Stockfish's rating is about 3650 now, so effectively, the rating ceiling would be about 4350 right now, but you would have to beat Stockfish every single time over hundreds of games. One draw would plummet the rating.
The various pools will continue to attenuate over time. It's not a fully closed system, so new players introduce ratings points that get thinly spread across the whole ratings pool. Players that stop playing do not cause points to be removed, so, 5,000 could be theoretically possible in a number of decades or next century. A million? Not too likely unless you artificially produced it in a way that any observer would agree was "cheating" the ratings system, like playing endless bullet games with a server farm of obsolete engines vs. one top engine, and then "reintroducing" new engine "players" to inject rating points into the system.
The question is though, at those levels, is it possible for a chess program to actually be 1,000x better at computing, but still not be able to beat the lower rated engine 1000x more frequently. Just because the lower engine still isn't just going to lose easily. If it manages to find a defensive fortress for example, no matter how much further the higher level program can calculate, doesn't mean it it will be able to breakthrough to win. It may not require as high a level to play perfectly defensively, whereas the level of the higher one won't matter if there's no way to breakthrough. Ratings are affected by game results, so they may end up evening out eventually in rating even if one is 1000x the ability of the other, due to the fact that it can't win enough. To put it another way, the 4000 rated engine might be beating the 3000 rated engine 10x more frequently than it beats the 3400 rated engine, which is expected, but yet struggles to win 90%+ of games against the 3400 rated one itself.
