Estimates will always be off compared to a plugin like wakatime tracking the real amount of AI generated code vs human written code.
If AI is a threat to software engineering, I wouldn't expect many software engineers to actively accelerate that trend. I personally don't view it as a threat, but some people (non engineers?) obviously do.
I'd be curious if any OpenAI engineers can share a rough estimate of their day to day composition of human generated code vs AI generated.
