I'd say if you feel stuck and feel like you are not progressing, it might the right time to look for a new challenge?

That turned into trying out simple hello world programs and eventually I found it started becoming way more interesting than my current job and found a job using it.

A lot of my network often read books and attend conferences so there's that too (not my cup of tea but everyone's got their preferred outlet)

After being in the field for a little while you come to realize that languages are just dialects on the same core, new tech and frameworks are mostly just different wrapping, and that the core tenets and fundamentals that you know will always be there in some form.

What will help you with longevity are things that are not traditionally looked at as SWE skills. Things like empathy for users and other developers, communication skills, being able to iteratively create user value, understanding costs of delays and that perfect is rarely what we want, etc, etc, etc.. Solving logic issues with algorithms is such a minute part of what we do, and the part most likely to be automated at some point.
