"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 CL…
Answering to preemptively asked question that doesn't appear in TFA: yup I sure still do.
If anything compared to the 486 days, back when Eight Megabytes And Constantly Swapping was a joke that made sense, my computer now instead of 8 MB or RAM has 32 GB or RAM (so 4096x more RAM, or 2 exp 12 more RAM: something something about transistors doubling every 18 months and all that)...
Who's laughing now? ; )
Seriously though: Emacs with native-compilation, tree-sitter and LSP support (and stuff like Magit and ripgrep integration too) makes it really amazing.
