I thought that this was me ("The industry in which I have based my entire career just doesn't excite me anymore."), but then I realized I actually am mostly just interested in programming the way some people are interested in any other skill or machine. Some people learn guitar because they need to make music and play out. Others just love playing the guitar, even and especially when nobody is watching, for its own pleasure.
To me, there is no greater toy than a programming language. ChatGPT is neat, but it isn't a programming language. Same for blockchain or agile or whatever other trend is happening in the industry. Some of the trends literally are new programming languages! Golang is really fun! So is TypeScript!
Some trends or technologies make programming even more fun (in my opinion anyway) and I embrace those feverishly: distributed version control, CI/CD, pair programming (sometimes it's even more fun with a friend!), configurable linters like Perl::Critic, Intellisense, JUnit-style testing frameworks. All this stuff helps me feel more in control of the computer (or distributed cluster of computers), which I've discovered is the main thing that gets me off about programming.
I'm even still hopeful that LLMs will have some role to play in my having more fun with programming. I've tried CoPilot and so far it hasn't grabbed me, but maybe this will change. In any case, there are clearly other people having fun with it so I guess that's good. Maybe somebody can find joy by debugging GPT-4 prompts the same way I enjoy pouring over stack traces.
