As if obscure knowledge is worthless. Trading the opportunity to make money for obscure knowledge is the whole value proposition of a Ph.D.! If one doesn’t value obscure knowledge, yeah, a Ph.D. Might be a bad value proposition for that individual.
Nope. You can go ahead and make a startup which can fail and then you're left with burnout and an empty bank account. Wasting time is an integral part of life.
