I hear this a lot, but also I'm curious. How can you really forget coding?
It doesn't seem to me a thing that I could suddenly forget?
Without AI I will feel frustrated that I'm now much slower, but ultimately it's just describing logic. So I'm a bit skeptical of the claim.
My brain effort is also on other things now, such as how to orchestrate guardrails, how to build pipelines to enable multiple agents work on the same thing at the same time, how to understand their weaknesses and strengths, how to automate all of that. So there's definitely a lot of mental effort going into those things.
If your internet died you would likely be worse at programming that you were in 2020. I think is what people are getting at.
If you are not practicing an activity consistently, you'll forget some of the finer grained aspects. When I'm coding, I subconsciously create a continuous logic map. Having someone or something just generate (and generate so quickly) destroys that and makes it easier for bugs to slip through.
