what does chess really serve the human? is it just a way to enjoy time well-spend or personal improvement? or does it help to evolve our gene somehow? I always feel smart people spending so much time and part of their life on chess, is like a waste of talent, that could be well put into other things that are more meaningful to the society, such as, inventing new system, improving existing design, fixing some real issues, or even teaching coding to the public etc.
