Yes I imagined his idea of "criticizing" amounted to abusively yelling at people. From what I've seen, the way people win Nobel prizes is by working their lab 24/7 like a slavedriver. I actually have seen psychopathic professors yell at female lab members until they cry. I knew one guy who complained about it. He apparently got much more productivity out of yelling at the guys. Pretty dark humor if it's a joke.
