I think the author needs to come up with a different title because it's highly misleading.

The author's premises are also highly exaggerated. For starters, the game of chess has not stopped evolving, because our chess engines continue to get stronger and stronger. The strongest engines of today can crush the older engines from a few years ago. This goes to show that even the elite machines haven't completely figured out chess; the smarter engines are going to continue to push the chess meta forward. In that sense, chess creativity and intuition hasn't stalled. We've just reached the point of collective knowledge that only machines can improve on chess theory.

Second, it's not like GMs are playing bad or losing moves to bluff the opponent. In most opening positions, there are at least 3 or 4 moves that could be played to still maintain winning or drawing positions. When GMs pick "suboptimal lines", they're picking maybe the 3rd or 4th best option that's still objectively a good and viable move from an engine's POV. Nobody is playing bad or losing moves on purpose, that simply does not work in chess.
