My point is that there are so many people in the world, and chess is very, very competitive. If hard work and study alone were enough, there would be no such thing as super GMs. The smallest advantages are often very telling. And at the super GM level, having a better inborn ability to see the board and understand the pieces relative to one another in space, and remember theory, is decisive.
To say that the average person, even with a million years of study, could play at that level is preposterous. If you don't have the neurons you just don't have them. Good luck in a future life.
Ofcourse anyone can be a Super GM in their DREAMS...why not?! dreams are free...
