I more often heard the argument, they are not useful for them. I agree. If a LLM would be trained on my codebase and the exact libaries and APIs I use - I would use them daily I guess. But currently they still make too many misstake and mess up different APIs for example, so not useful to me, except for small experiments.
But if I could train deepseek on my codebase for a reasonable amount(and they seemed to have improved on the training?), running it locally on my workstation: then I am likely in as well.
