I thought it was nearly impossible to do software development and not learn continuously? Can't imagine what a dev workday looks like when you aren't learning. You rarely ever do the same thing twice, and even if you do you learn from past mistakes and become more efficient.
So a dev is hired out of school to build CRUD forms in (VB6|GWT|Something similar). Most likely they master the technology in a few months and now just take new/change requirements and never deal with much beyond the original tech. In a big company where changes can take forever, the dev spends a lot of time waiting on new requirements, going to meetings and acceptance. Before you know it, a lot of time has passed and the dev is still just building CRUD forms in whatever technology that happened to be put on when they were hired.
