The core should be in rust, verfied in lean, and the runtime should be in guile. Literate programming in org-mode should be a hard requirement. Package management should require patch algebra. Macros should be submitted to a leaderboard in a blockchain and yield flair in EUDC. M-x measure-beard-length should require 10000 hours of logged usage and unlock the major mode infinity-categorization.

Tongue-no-longer-in-cheek:

I reckon the C core of Emacs is some of the most battle-hardened code out there. Verification, a-la SEL4, is probably irrelevant but still nice. Guile is modern and performant but Elisp is still its own little joy. Literate programming is always nice until it gets in the way. Straight is good enough for me now. Macros are always cool and a leaderboard would be fun, but patch algebra is really nice, see jujutsu nowadays. And beard length is gendered and so only partially admissable. Infinity categories are way out there and always good for a reference.

Yes

Ok, you had me for the first three sentences.

Implemented mostly in Guile, with just some native primitives/kernel bits in Rust, makes a lot of sense, for a programmer's application platform in the spirit of Emacs.

Since I agreed with all of these, I’ll add some more non-ironic, idealistic wishes:

Plugins must be written in sandboxed WebAssembly so you can know what a plugin is capable of without reading the source code. The runtime must be portable so it can run in wasm32-wasi.

relevant: https://github.com/remacs/remacs#rust-heart-emacs although as of this message it says they've given up in favor of https://github.com/emacs-ng/emacs-ng#contributing which does mention Rust but seems to be ... a lot different from Emacs so I guess they're really going all-in on the "NG" part

for the non-tongue-in-cheek, also relevant: https://www.emacswiki.org/emacs/GuileEmacs#h5o-2

When I saw “should be in rust” my instinct was to flame like nobody’s business, glad I kept reading. Lmao. Good slow burn.

Though, not to put too fine a point on it, I know it was in jest, but the core implementation language is the least of my concerns. As long as it is extremely portable, compiles fast, and runs on virtually anything, then whatever the core is, doesn’t matter much to me.
