Respectfully, you're describing workflows that very few people use today. Patches over email or chat? I've only seen that use at any scale with Linux kernel development. Tricky tasks on remote servers, editing files on remote servers? Most places prefer immutable servers, which run peer reviewed remedial scripts via Ansible/Puppet/Chef/Salt.

Org mode is one of the few unique bits of software available only on Emacs, but you can get 80% (if not more) of its functionality with markdown notes and regular email/calendaring software for 20% (if not less) of the learning curve.

EDIT: And I'm not ignoring Spacemacs and its kin. Yes, they are more user friendly, but they still do not follow many of the common OS UI models, and you still are interacting with a single-purpose programming language for any customization. The abstraction falls apart quickly when you try do do something more powerful (like opening the package manager).

Not to mention, the last three times I tried to do Go development in Spacemacs it would freeze in an infinite busy loop. It's unfortunate that a broken mode can completely hose the entire editor in this day.
