(Disclosure: I'm getting a PhD in CS now)

> The hard part of startups is product: knowing what to build, and being able to build it

Funny enough, this is why I think a PhD is undervalued by many. You spend years focused on a single area, sometimes pivoting topics, and getting hands on experience with operating solo on the outskirts of a particular field.

The overall point of the degree is you learn how to learn. The nice part is you have the padded walls of university equipment, funding, and time; So failure isn't terminal, just an opportunity to figure out what didn't work.

There's a few reasons how and why this message got distorted and lost in modern academia (honestly it would be a great subject for a book). It's no mistake that better known programs and programs with ties to a stream of successful startups are also the ones where there's a culture of builders and makers.
