I'm not even sure if they teach anything meaningful these days at colleges. I spent a significant part of my life in academia, and I loved it, but it was many years ago. Now it looks like most of the meaningful substance has evaporated from higher education, and it has been replaced by the meaningless fluff such as forced diversity, inclusion, snowflake culture, etc. It is so sad to see this nonsense it totally overtaking what used to be a temple of real education, science, reason and logic...
