The loneliness on the top is unbearable. Most people who get to the top don't seek a external validation of their competence. So they ought not to be affected by loneliness. Unfortunately in games, wars and art, other people have an effect. In games the incompetence of the opponent while initially entertaining immediately loses the pleasure it gives. It quickly turns in boredom – a search for a worthy opponent. Boredom turns into philosophical inquiries about purpose, and it is at this point most people fail. They often end up finding the wrong purpose. Religions offer canned purpose, ready to use without thinking. Unfortunately it can never satisfy a thinking mind and deludes it. This is what happened to Fischer. Even the smartest minds can be indoctrinated using these philosophical vulnerabilities in the mind.
