Who keeps claiming these models are meant to replace engineers?

OpenAI, xAI, Anthropic, Google, MSFT, Spotify, Duolingo and NVidia - those are the ones that come immediately to mind. They're either selling the AI (or the tools to make the AI) or hoping against all hope that they're on the right side of bubble history.

If we soften the claim to "increase engineer productivity" I think something like 70% of engineers would also agree. If you tack on "if applied wisely" then you'll probably be up to 95% of engineers

the remaining population of linkedin users?
