> Compare that to understanding C or UNIX. There are skills that decay much slower than others.

Correct! Knowledge around C, Linux, CPUs and optimization last many decades.

Knowledge of tools and libraries in high-churn languages last years at best.

I've found a lot more career happiness with focusing on a long-term domain (networking), long-term expertise (testing), and a stable tech stack (python, c, etc). Got pretty close to burnout chasing the latest libraries in the latest languages a few years ago but now I'm very happy making sure the product is cutting edge but the tech stack is stable.

This is what I'm trying to do as well now (move from full stack web dev to something more in the lines of what you're describing). Any tips you can remember on how to make the move?

[EddySchauHai]

I spent a bit of time practicing these tech stacks in my own time and fitting them into prior jobs where I could, but honestly it’s worth just getting out there and applying.

What is your role now (just curious), what do u mean by testing? And what was your prior experience before making this move?
