The main problem is the people who spent the best years of their lives in kollel thinking that they were going to become the Rashkebehag, and then didn’t get the shteller they imagined they would get, and are now inwardly bitter people sitting in their basement in their undershirt (take that either literally or figuratively) half the day writing deios to the coffee room. They think that just like the Rambam and the Vilna Gaon understood everything about the secular world from Torah, they do too, and therefore they think that they know everything about everything, from physics to medicine to law, when they really know very little about anything.
