The magic of the game to me is/was in working hard to figure out how to out-think, out-strategize and even trick your opponent. And, yes, that still exists. World Chess championships are not robotic regurgitations of prior games. Some aspects of them might be, but there's plenty of hard thinking applied as well. All I am saying is that you reach a level beyond which the only way to progress is to become a database and that's simply not interesting to me. I also happen to think it is an absolute waste of time unless you happen to be particularly gifted at chess and have aspirations on the world stage.
This is the reason I don't encourage my kids to continue playing competitive chess beyond a certain stage. One of my kids was killing it in local competitions all the way up to the stage where kids started to become walking databases. I wasn't going to do that to my son. There are better things to focus on in life.
The other realization was that getting better at playing chess didn't make you better at everything else. It is a fallacy to think that because someone is amazing at chess they have superior reasoning abilities in other domains. That is rarely the case. There are early to mid-stage cognitive gains to be had from learning and playing chess. Beyond a certain point getting better at chess simply means you got better at chess and nothing else.
