Sometimes I get 1 good line from that. Sometimes I get 30. Usually I get 10 bad lines and have to type a bit more to coax out 8 good ones.
It just looks faster but typing was NEVER the bottleneck for coding.
Where it really flies, though, is building tooling around a well known API. FML if I ever have to write AWS CDK or AWS API calls without an LLM again. You're looking at ages of reading through really bad docs to get it going.
For that, which is a 1% task of convenience for most jobs, I can use most LLM output verbatim. But that's like I said less than 1% of the job, and only then when the core software is done.
