This is the path that the GNU Mes and Guix folks are taking: https://guix.gnu.org/en/blog/2023/the-full-source-bootstrap-...

(sans LLMs -- I believe they have a Scheme (GNU Mes) that can be compiled from their 357 byte bootloader, and that Scheme can run a C compiler that can compile tinycc, and I think there's a path from tinycc to compiling gcc. I'm not sure how far it can get after that -- this blog post[1] implies that you still need a binary of guile to run Gash, which is a POSIX shell written in Scheme. I'm guessing the plan is to either simplify Gash or complexify Mes to be able to remove Guile as a dependency.
