If he says chess is a draw--he means chess is a draw.
Can you send me some links to their actual quotes? I won't try to read minds. Let's see what they actually said. Please show specific references to where I can read what they actually said. I would like to know if they are talking about grandmaster-level play, or mathematically perfect play.

maybe this will show up?
White to move, find the best moves. [there is only one set of best moves in this problem]
There you go again: after playing 50 non-best moves, you are introducing an ending where a best move is possible to spot. I’ve already described this situation: it proves zilch.
Actually you are incorrect. The position and solution DOES prove something. It proves that sometimes humans can find best moves that a strong chess engine cannot find.
No, it proves that a strong engine of today is a pure joke of tomorrow. I’ve been saying this from the beginning, but who’s to listen?
