I don't know where you're working but LLM enhanced development has skyrocketed our rate of feature development. As an example, a project roadmapped to take 7 months was delivered in only 4.5 because of CC/Codex.

I'm confused how anyone could believe it isn't an enhancer, unless they have refused to use any of the technologies.

You're measuring success with time to delivery, that's a reasonable metric. Same with volume of features shipped. Also good. LoC or tokens burned... not so much.
