I never understand why folks who have bad individual experiences end up extrapolating that experience to represent an entire area (field, subject, industry etc.).

Or to put it another way, I understand the impulse, buy why not self reflect a bit to figure out if that impulse has merit (it doesn't)?

Surely the fact that, overall, we do make meaningful and real scientific progress over time (we may now have room temperature superconductors!) shows there is more value in the academic process than there is problem, though obviously the problems are substantial and create significant limitations.
