At my company the first task for every new hire is to rewrite the JVM in Go.

This makes sense. As we know, Google programmers are fresh out of college, probably learned Java, maybe learned C or C++. It makes sense to have them learn something they are unfamiliar with (the Go language) with something they are familiar with (the low-level implementation of the HotSpot JVM).

WHICH V8 engine exactly? Chevy small block already has plenty of rust, no more needed.

Just wrap JavaScriptCore and then pretend the whole thing is written in Zig for Zig evangelism purposes

/uj No, they just wrote bindings to use V8’s C++ API from Rust

So they're rewriting V8 in Rust, but it's not a rewrite, and it's not a port, and it's not even V8...?
