>In Emacs, I read my mail, I organise my agenda, I write technical reports, blog posts, I wrote my entire thesis in org-mode. I collect research notes in Emacs, and a journal. I do my bookkeeping and accounting in Emacs.

No one cares (other than Emacs users). There are better tools designed for those purposes. There's a reason the UNIX philosophy of doing one thing well is still so popular and widely used. Rather than configuring and spending hours on buggy, poorly developed and indecipherable systems like Gnus, org-mode (it's like an Emacs with an Emacs, just ridiculous) etc people instead choose tools that are far better, more intuitive and works out of the box and everywhere.

> I edit remote files, I edit files via sudo on my machine.

Any decent editor or IDE can do that.

>I control git.

VSCode support for Git (and Github) blows everything else out there. And so also for languages like Python. Emacs support for any language which is not a Lisp dialect or C is horrible.

> I've been a dev for less time than you have by about 6-7 years, but I can honestly say that no other tool could even come close to replacing Emacs.

I very much doubt you actually tried to use anything else.
