> It's not clear to me why you would want your editor to run in as many environments as possible unless you're a system administrator?

All I really was trying to say is that one may find themselves in a more limited environment at some points, I was not so much thinking of remote editing for the reason you mentioned that most developers or even system admins(unless restricted for security reason or some other) can just remote in and most editors these days do this well. but in a situation where one may be installing their system or their graphics acceleration has broken for what ever reason and now one is without their trusty editor so although I hardly every use emacs in a tty or pty it's a fallback in case something goes wrong so I can fix it while still using my editor.

>that the editor can open 60,000 line code files instantaneously syntax highlight all of it using trees that are and be butter smooth and responsive the entire time I'm searching through making multi-cursor edits or moving through the file.

this definitely sounds interesting, emacs when dealing with very large log files and such is not always fantastic and some features become painfully slow or completely unusable .

Your other points on the AI features are interesting I have been using Aider and tried aidermacs but ended up going back to a shell buffer with some basic commands to switch back to the buffer and other features to control it, while in one of the code buffers. So will definitely look at some of the AI features when I give it a spin.
