Some time ago, a former student of mine went to a national scientific conference. After returning, over lunch she said to me that she learned two things.
Do not, under any circumstances, do a Ph.D. This was basically advice and the underlying message she got across the board. Nobody should do a Ph.D., because the number of people getting jobs that need a Ph.D. was, according to some estimates she heard at the meeting, 10%.
PIs are horrible people. Didn’t matter what the career stage was. Every grad student and post-doc was unhappy with their supervisor.
I hear this and think... holy crap. How has this all gone so wrong?
