I've been coding since the 70s . using a modern IDE or VSCode has nothing to do with age
Maybe with 50+ years there's a limited amount left to learn, but with my 25 I'm still picking things up regularly.
So it's usually more junior and less experienced developers who ask "how do you do that" - sometimes with wonder, sometimes genuine confusion.
My answer is never "it's simple" or "it's just" but always something along the lines of "it's a culmination of using the same tools consistently for many years", usually followed by "hey have you seen this trick too".
