Ekhem. When Chrome was announced there wasnt Rust. And Java was a programming language for slow moving systems, with many a flaws and its own classes of footguns.

I dont think they had much of a choice in 2008. Now? Sure. I bet a rust port is in the works.

This is correct (I worked on chrome in 2008) it's important to remember that chrome's renderer was webkit, an existing c++ stack.

Chrome's stability innovation was to run different tabs in different processes, and the security innovation was then to sandbox those processes.

Rust would have been super nice but it wasn't an option then, and of course let's remember that Rust was developed by Mozilla specifically with the goal of making safer browsers.
