Please do not take advice on cognitive science, personal health, finance or relationships from renowned experts who have found immense success in entirely different fields of knowledge.

John Carmack is a very intelligent person who can teach you a lot about many extremely complex engineering-related matters.

Applying his advice on health and work-life balance without a full understanding of the many variables that skew his perspective and his own daily life is probably a bad idea.

Expertise is not automatically domain-transferable. Anyone claiming otherwise is suffering from hubris, or star-struck.

I understand the direction of the comment although I think it can only be applied to very limited situations. The argument seems to be like: do not regulate or discredit drugs because there is some people successfully self optimise with them knowingly taking certain risks...
