My problem is the almost dogmatic indoctrination that goes along with it. My cousin's Intro to CS class was taught by a professor who spent about a third of the time basically parroting Stallman (he actually would regularly bring up blog posts and articles on the screen and read them to the class...) and screaming about how everyone needs to use either Vim or Jetbrains tools. That isn't teaching. That is pushing an agenda. And it just makes for worse students and hell for those of us who still spend some time with the interns and new hires.
Always explore new and better tools. But understand why. Sous-vide is awesome and has the potential to make some of the best food you will ever eat. But it also understand that even a "worse" method can be much more efficient or effective.
