"Is anyone still using emacs?"
Yes, 34 years and no plans to switch.
Emacs cursor movement keystrokes are quite widely supported elsewhere too which use GNU readline or implement at least subset themselves.
Those work well also besides shells with Chromium/Chrome/Safari etc. many browsers input fields (address bar and text area). Cisco IOS, Juniper Junos, Netscreen load balancers too etc. IMHO makes jumping around CLI much much convenient and faster than moving hand to reach cursor keys.
My only gripe is that Firefox and its derivatives it doesn't work any more. Long time ago it did work. And I have no idea why feature was dropped some rewrite.

Firefox emacs bindings still work on Mac since everywhere on macOS supports emacs bindings, nearly.

I have never used emacs seriously as an editor, however, I couldn't work without magit. I even manually build emacs 28 so I can re-use the same set of magit configure files.
Nearly 40 years for me. Wow! I’d note that MacOS input fields also have basic Emacs bindings for cursor movement, not just shells and browsers. Works in MacOS Mail, Evernote, etc.
