Losing interest in SWE due to not feeling productive. Am I not cut out?

I work on the monetization stack at a FAANG. Lots of GPU training jobs, model iteration, that kind of thing. And honestly, the day-to-day developer experience is rough in ways that I don't think people outside this niche fully appreciate.

Reproducing issues is a nightmare This is the big one. Something goes wrong in a training job, and to reproduce it you need: a build (30+ minutes), available GPU capacity (good luck), and enough time on the cluster to actually run the thing. Chain those together and you're looking at half a day just to confirm a bug exists, let alone fix it. Sometimes capacity simply isn't available and you're just... waiting.

Dev servers are painfully slow. My devserver lags constantly. Basic editing and navigation feel like working through molasses. I don't know if it's resource contention or just undersized machines, but it makes everything take longer than it should.

PRs are full of AI-generated slop. More and more I'm reviewing code that's clearly Claude/Copilot output -- verbose, over-abstracted, weird variable names, unnecessary error handling. It takes longer to review than hand-written code because you can't trust that the author actually understands what they submitted. Sadly, the company is all in on AI and AI usage like probably even a metric for performance.

It's becoming impossible to understand the stack end-to-end. Everyone is writing AI-assisted diffs and being encouraged to do so. The deep knowledge that used to build up naturally through writing and reviewing code isn't accumulating anymore. We've had a record number of breakages recently and I don't think that's a coincidence -- but leadership is blind to it. By lines-of-code metrics AI is making us faster. By breakages, it's making us worse.

I like the problem space and the scale is genuinely interesting, but the tooling and infrastructure make the actual work feel like a slog.

Anyone else in a similar spot?
