Not in the present circumstances, no. The interesting thing is if it would strike a match with the current disaffection with academia (perceptions of must-have-bachelor’s-for-any-kind-of-job student loan rackets and stressed-out researchers who spend most of their energy gaming administrative systems and grinding out cookie-cutter research tailored to fit standardized bureaucratic metrics for acceptable tenure-track career path progress), cause more young people who think they are talented and exceptional to drop out, and what they will do once they have and if that trend might continue far enough to change the wider circumstances around academia.
