IDEs have changed a lot in the last 50 years. Just like we shouldn't advocate for hand writing assembly for all code, we shouldn't be stuck using CLI tooling the same way.
I share your apprehension regarding the current AI landscape changing so quickly it causes whiplash but I don't think a mindset of "it's been fine for 50 years" is going to survive the pace of development possible by better LLM integration.
The reason that tools have not changed that much is that our needs haven't changed that much either. Even something like `find` or `ffmpeg`, while complex, are not that complicated to use. They just require you to have a clear idea of what you want. And the latter is why most people advocating for LLMs want to avoid.
IDEs have not changed that much. They've always been an editor superchaged with tools that will all share the same context of a "project". And for development, it's always been about navigation (search and goto), compile/build, and run.
