Didn't the servo team mostly dabble with Rust? What a bad idea from the very beginning to invent a new language and base core components on it when all you have to to is speed up an exisitng product and you are already using the fastest known language fot that task (--> C).
A slow Firefox was an architectural problem not because of choosing the wrong tooling.
I can’t tell if this is a sarcastic remark or if you truly believe speeding up something as complex as a browser is a cake walk.
Two big reasons Rust was invented was to (1) easily parallelize the renderer without introducing many bugs (2) speed up the browser without introducing many exploits.
It’s common knowledge now in applications like Chrome (and even Windows) that memory errors are the largest source of CVEs and that type of exploit is almost impossibly difficult to cause in Rust
