Are all respondents from US? Are they using it at work or at home for pet projects? What's the median size of the company they work at?
I'm surprised it's only at 72% to be honest.
If I'm hiring a junior/mid level guy, I'd want this person to be good at using LLMs to increase productivity.
It is difficult for me to imagine how an LLM would be any help at all in the work I do, but I think that "software engineer" covers a great range of different kinds of work these days.
