I think 20% is easily believable. LLM may not do more complex functions or work with your data, but a lot of the busywork of coding is done almost instantly.

I think 20% is easily believable. LLM may not do more complex functions or work with your data, but a lot of the busywork of coding is done almost instantly. Just not having to look through library docs or sort through StackOverflow is already worth 10%. I don't think LLM will replace software engineers anytime soon, as a whole, but removing the need for the bottom 10% is not a stretch at all. That has massive implications for salary, imo, except for the top end.
