content: You manager just sounds like a typical industry coaster. There are people who actively learn about and pursue the latest tech and there are people who just coast. He is just coasting. He's dead weight. It has nothing to do with IDEs or anything else. It's his attitude. He got comfortable with something a long time ago and can't be bothered to learn anything new. Those people are cancer in an organization and end up holding the entire group back because they can't be bothered to learn enough to move forward with the group.  People who assume "compilers will fix it" are just as lazy as the coaster and their effect is just as toxic. Mountains of poorly written code implemented by people who can't be bothered to learn anything about algorithms or optimization for the environment they're working in. These are personnel problems, not tech problems. They're the same kind of people responsible for those "engineering" disaster type shows where the problem is typically the crew that built the thing (meh, good enough), not the group that engineered it.
