All this IDE churn makes me glad to have settled on Emacs a decade ago. I have adopted LLMs into my workflow via the excellent gptel, which stays out of my way but is there when I need it. I couldn't imagine switching to another editor because of some fancy LLM integration I have no control over. I have tried Cursor and VS Codium with extensions, and wasn't impressed. I'd rather use an "inferior" editor that's going to continue to work exactly how I want 50 years from now.
Emacs and Vim are editors for a lifetime. Very few software projects have that longevity and reliability. If a tool is instrumental to the work that you do, those features should be your highest priority. Not whether it works well with the latest tech trends.
Fortunately, alien space magic seems immune, so far at least. I assume they do not like the taste, and no wonder.
