> LLMs saving engineers and developers time is an unfounded claim
By whom exactly? If I say it saves me time, and another developer says the same, and so on, than it is categorically not unfounded. In fact, it's the opposite.
You've completely missed the point if you don't understand how telling other people that their own experience in such a large field is "unfounded" simply because it doesn't line up with your experience.
> we have a way to go before we can say anything concretely
No YOU do. It's quite apparent to me how it can save time in the myriad of things I need to perform as a software developer (and have been doing).
