If I were Google I'd try to rewrite Chromium in Rust. The FFMPEG folks should try porting the whole codebase to Rust too. They can always keep the legacy versions for legacy computers (my old n270 netbook can barely play 720p@30FPS anyway, and it's too slow to downsize 4k video to 720 or 480p...), so a bigger amd64 machine will always be -reallistically- needed for anything else than <=720p consumption.

What folks at Ladybird did this year. Started adopting rust for part if not all their engine.
