Bun is going this route because their proposed fix wasn’t great. https://ziggit.dev/t/bun-s-zig-fork-got-4x-faster-compilatio...
Cannot imagine this agent rewrite had anyone review any the code (you can’t at that speed).
I’m positive this will go extremely well :p
Fwiw, that's not the stated motivation for the rewrite experiment. In fact, the Rust rewrite is slower to compile than the zig code when compiled with their internal fork of zig (tho it is faster when OG zig is used).
I don't want to infringe upon your right to speculate. I just want to point out that your statement is at best a speculation.
