I finished a Ph.D and became a tenured professor (top of the greasy pole) and I have no regrets despite not being part of academia anymore. The experience of doing a Ph.D changed me for the better and gave me the confidence to take the risk to start my company. We don't train too many Ph.Ds, we just undervalue them outside of academia.

Too many students end up on the Ph.D railroad without experiencing anything outside of school.
