It's a knowledge base that can explain the knowledge it returns when you ask, how is that not useful in a professional environment for production code?
I mean if you assume all devs are script kiddies who simply copy paste what they find on google (or ChatGPT without asking for explanations) then yeah it's never gonna be useful in a prod setting.
Also you're very wrong to believe every technical need or combination of libraries has already been implemented in open source before.
True, but hey, even if it's not production code, it may be an ad-hoc thing that never gets push to production, it may be code reviewed by C++ experts and improved to production quality. At very least, someone saved four days with it, and could use the time for something, maybe something they are expert at. Isn't that still good?
Most of the time saving time is just an illusion. When that code will needed to be changed, people will spend more than 4 days debugging and understanding it. The mental model of it was written by AI. It can make sense or not at all. You’ll figure it out after 4 days.
People talk about completey different things. The article was about Google using LLM-s to generate code, not people making 80 lines with them at home. There is a huge difference. I don’t see any problem with the latter, but with the former there are many problems.
I have shipped production code using LLMs in languages I did not study approved by seasoned SWE's is evidence that an acceleration is happening.
