00:08.500 Q: Have you considered using CRDTs to share buffers between threads and merge any concurrent edits automatically?
01:05.874 Q: Why hosted on GitHub? GitHub is nonfree. Is it possible to report bugs/send patches without using GitHub?
01:22.960 Q: Do you think it's possible to achieve 100% compatibility with current Emacs code?
02:11.913 Q: so you're re-implementing elisp in rust? have you considered using a more modern lisp, such as scheme? [11:03]
04:01.400 Q: Do you have specific features from the Rust compiler that are missing (or are nightly-only) that you would take advantage of?
05:26.880 Q: Can remacs be reused?
07:23.600 Q: What are you thoughts on the GUI layer. Any plans on how to reimplement it?
08:21.240 Q: If money could fix the problem, how much would it cost to ship this with feature parity before 2026?
09:28.350 GObject implementation
09:56.600 Q: elisp is implemented in c, so if you're not implementing elisp in rust, are you using/keeping the c implementation of elisp?
10:42.680 Clarifying rewriting Elisp in Rust
12:57.908 Q: Will your Rust implementation also be able to run Emacs bytecode? Or are you implementing it at the Lisp level?
14:20.100 Q: Is it possible to bootstrap with just the bytecode interpreter?
17:03.960 What would it take to bootstrap Guile in Rune?
