Academia is no more motivated by a honest interest to understand things around us, raise questions and spend time deeply thinking and genuinely coming up with solutions that really make sense and bring change to the world.

A lot of researchers are very mediocre and they treat research as a simple career where they superficially advise a bunch of PhD students. A lot of those researchers neither think nor raise questions nor make meaningful contributions.

Exacerbated by research grants which favours researcher with lots of publications regardless of the quality of the research (usually real honest high quality research takes time and produces much fewer papers). Those researchers thus end up chasing low hanging fruit just to increase their paper count, making everything they do shallow and full of bullshit.
