I'm still quite young, but I notice it is harder for me to learn new concepts or programming languages than it was when I was a teenager. I can imagine many programming jobs have little room for learning. I'm still a PhD student so learning is part of my daily "work". I don't have a family to take care of either. I can imagine that in 10-20 years I will hardly have any time to learn new things and will have to rely on what I already know. Also I frequently hear people say "programming is easy" or "you don't want to be programming all of your life, right?", so maybe people think they don't need to study new languages, because they think they will actually need to do less programming in the future as they get more senior jobs. I'm not sure if they are right or wrong. I really hope I can spend a large part of my life learning about new things, and I hope those things I learn will help keep me employed. At the same time, it's hard to predict whether the things we study today will still be relevant by the time we are in a position to apply what we learned.
