A benefit of the these modern players is the latest opening theory.
Humans discovered the most logical and accessible ideas first. That's why it's useful to look at the games of the (objectively tremendously strong) players of the past like Capablanca, Lasker, etc. (Anderssen, Morphy, Steinitz, not so much, although Morphy is good for tactics / active play in open games)
Modern players stand on their shoulders, and play games and ideas that are harder to understand. So you start from the beginning like all the humans who came before you ![]()
Opening theory, in isolation, is disgustingly pointless. Real opening study means learning about the middlegames your opening moves are aiming for. Reaching the end of memorization on move 10 and having no clue what to do is... I don't have words for how wasteful that sort of study is.
If you want to study openings here's my advice: study a collection of GM games that feature that opening. Start with historical games, and mix in some modern games too. After a few 100 of those, then you can use a database to hash out a specific repertoire.
AND IF that advice sounds not very useful (and for most people it should not strike them as useful), then ignore openings for now. You need to learn the basics in all the other areas (endgame, strategy, and tactics) before you can properly tackle openings in the way I describe (by looking at GM games and understanding the middlegame positions your openings will reach).
That's my advice, FWIW, as a non-titled player. If you want a GM's advice go ask a GM.

Hey, you actually made me laugh a bit though, so this has a good outcome
(and it was good advice)
Well I hope someone or something else will make you laugh again today. As much as I’ve enjoyed this forum, I need to get some sleep. It’s after 4am with me, and I have to get up in 3 hours. I wish you all good night, guys
