And what about Org, Org-Roam, Anki-editor, pdf-tools and org-noter, Eshell, gptel and chatgpt-shell, Transient, Vertico, Consult and Embark, Dired, Notmuch and mu4e, elfeed and elfeed-tube, consult-omni, gh-notify and code-review.el and many other nice things?
Sure, Emacs has many deficiencies - nothing is ever perfect. I too, would love to find something better, where those deficiencies are not. But tell me please, which alternative does allow you to do any of these things "reasonably" well?
Tell me, in which editor I can be taking my notes while also sending http requests, and queries to an sql database, while transforming the results in a higher-order language and then spitting out the data into a chart? Where I can also mark things in my notes for spaced repetition, without moving them anywhere, without converting anything. Where my notes can have LaTeX embedded formulas. Where I can type 'RFC 7230' in plain text and my editor would intelligently know what that is and allow me to browse the relevant document in-place. Where I can open any pdf and it would automatically locate my annotated notes. Where I can control the playback of any video - YouTube or whatnot, pausing it for note-taking, grabbing entire paragraphs of its transcript and putting them into my notes.
Tell me, which other editor has the notion of 'indirect buffers', where you can modify the same file working with it as if you're editing multiple files - where I can edit my code comments, treating them as if they are in markdown? Where you can freely edit your directory structure, using all editor features like multi-cursors and other things?
Tell me, which other editor allows me to search things in so many ways. Where else can I type a single query once and it sends out requests to Google, DuckDuckGo, Wikipedia, my browser history, GitHub, etc. and consolidates the results into a single buffer?
Bottom line: there just doesn't exist a reasonable option that is better than Emacs in the sense that it is free from its deficiencies and yet so versatile and powerful.
