I'm doing something ambitious. I'm taking a radical approach to improving rust compile times. The reason it is radical is it involves building a brand new rust compiler. This was inspired by a project I started[1] about six months ago to teach agents to build C++ compilers from scratch. I wrote a (long) series of blogs about the process[2].

After iterating on many agent built C++ compilers, I now have a version that compiles about 4x faster than GCC and Clang[3]. I think i can extend the same approach to rust. I'm still a ways from the rust self-hosting stage but early results are promising.
