I very rarely use autocomplete on Emacs, except hippie-expand. I have yasnippet installed but I have never used it. I just checked, it's not even key bound to anything.
I work on greenfield projects so I see my fair share of boilerplate, but honestly, it's just a minute part of work that's almost meditative to write a little bit of trivial code (i.e. a function signature) in between sessions of hard thinking. Writing boilerplate is very far down the list of things I seek to optimize.
Couple of years ago I was (as a human being, not my career span) 20. Spare for the usual StackOverflow / blog snippets, that was my experience and I suppose most of those just starting out. I think it's very recent to have fresh grads that barely type code themselves.
Yes, I write a lot of things in notepad++ actually, every single character. It really feels like a craft and gives me the same joy as others experience with woodworking or gardening.
I on the other hand am a software engineer, so writing code is part of the job title.
