Fascinating take on why public intellectuals have short shelf lives:

This is a big part of why I intentionally try to keep "doing foot-soldier things" (notably, coding, and exploring the world regular-person-style rather than entourage-and-limousine-style)

I've seen this same idea expressed in other terms, such as "the cloud vs the dirt". It's about having a grand vision while making a conscious effort to stay grounded in reality.
Fame gets to people's heads and offers the option to stop living an everyday-person life, but that life is where grounded wisdom comes from.
