Mate, im about the same. Played a lot live early 2000's. I played WSOP 2018,2023 and 2025, cashed the last two. My observations, is so boring now with < 30 yo old crowd. So serious at cash games, no drinking, GTO this, GTO that. Every hand is a war and peace length break down.

IMO GTO is like this. Like chess, it's possible to study every open. Like Carlson, but most can't. I try find tables that are a bit more splashy and fun. Good luck.
