If I felt the need to optimise things like infra setup and config at an early stage of a project, I'd be worried that I'm investing effort into the wrong thing.
Having an LLM churn out infra setup for you seems decidedly worse than the `git push heroku:master` of old, where it was all handled for you. And, frankly, cheaper than however much money the LLM subscription costs in addition to the cloud.
As someone who has been in this industry for a quarter century: no, you won't.
At least, not before something even worse happens that finally forces you to.
