Our tech lead was very enthusiastic about LLM-generated code for a minute. This lasted until the third or fourth time one of us reviewed a PR he'd so written and requested ground-up rewrites.
My guess is that, by this time next year, the vast majority of people and companies currently enthusiastic about generative AI will be pretending like they never had anything to do with it, a small hardcore of true believes excepted. The hype cycle will then begin anew with something else.
When Microsoft pivoted to security, they seemed to really mean it. They stopped shipping new features for something like 6 months, and spent the time hardening the OS. The results weren't perfect, but they made Windows not the total joke it had been.
