In fact, I think that teaching and encouraging to learn is the most important thing in SE. And that has to begin with leadership figures that don't believe their own knowledge gets obsolete after one year just because the latest framework got released.
SE should not be an art form. It should be founded in solid science and abstraction should allow us to keep our knowledge applicable. You're not a bad engineer because you never touched the latest hypetech or programming language. You are a bad engineer if you only consider yourself a "frontend developer with react on chrome".
All IMO, of course.
