So you're saying that the laws of physics don't imply any kind of upper bound on how good could anybody could become at anything?
Or maybe you mean that nobody could actually want to be better at something than they are capable of being.
Ooook mister smarty pants, If we live in a concious based universe then essentially saying atoms are not real but part of what we think them to be. Wouldn't it be fair to say that we could rethink parts of the atoms in our brain to be more abundant or responsive or even adaptive towards the goals of chess but not towards other functions?
If it is, I'm in trouble, I guess.
