This is why I am happy below the line of UI, mostly backend stuff now. That said I have never stopped learning new languages and skills.

Part of the industry. It moves so fast you blink and you are left behind.

They joy I have in my current post is I am free to push the language I work in (C#) so I can really explore the different ways of using it. Been in the same code base now 10 years, starting from C# 2 and the difference in old and new code is huge. Far more functional now.
