IME if anything, people are relying on LLMs for ops more than for development! Devops convinced management that ops isn't actually all that valuable and that devs can just do it. IaC is usually a mess of boring YAML based syntax that no one in their right mind want to learn anyway. Learning Ansible doesn't feel like a transferable skill unlike learning a programming language or paradigm, and in most teams the quality of the IaC stuff (abstraction, code reuse etc.) never mattered much.
As soon as LLMs became good, generating IaC stuff was like the first thing to go full vibe coding, at least for me. I'm proud of my craft, I don't produce bad code with my name on it, I very carefully review all the code changes etc. Devops YAML stuff? Couldn't care less.
