Nothing to do with employment. I was just doing a "home-cooked app"[0] thing for fun that served a personal usecase. Putting it on my resume would be a nice-to-have to prove I'm still sharpening my skills, but it isn't the reason I was developing the app to begin with.
What I think at least is the administration and fault monitoring of lots of random machines and connected infrastructure in the cloud might be left somewhat untouched by AI for now, but if it's just about slinging some code to have an end product, LLMs are probably going to overtake that hobby in a few years (if anyone has such a weird hobby they'd want to write a bunch of code because it's fun and not to show to employers).
You're right that a lot less people will be writing code like a lot less people are sewing these days but people still do it for fun.
P.S.: I really enjoyed reading moonbound :)
And learning new technologies in pursuit of resume-driven-development is fun?
I gotta say, if learning the intricacies of $LATEST_FAD is "fun" for you, then you're not really going to have a good time, employment-wise, in the age of AI.
If learning algorithms and data structures and their applicability in production is fun, then the age of AI is going to leave you with very in-demand skills.
