things ppl often get wrong in academia AUs (specifically ones in modern university settings with focus on graduate students & professors):
no one is spending enough time complaining about writing
hierarchy is wrong. your grad student TA is not a professor or faculty and might not even be considered an employee. that 32 year old man is not a full professor no matter how talented he is or how old you think 30+ is, and he should be talking more about "the tenure clock"
grad students only ever taking or TAing classes & never doing research or working on their thesis/dissertation. there are masters programs with no thesis component so i'm sure there are ones that have no research requirement, but you can't get a PhD only taking classes
everyone has too much money. but also if it's set in the US there's an obsession with accumulating student debt for positions that generally you would not have to take out loans for
relationship with academic advisor never sufficiently unhinged
not enough discussion of stats where it's obvious everyone only barely understands what's happening
