Realistically, are we ever going to get a full Rust OS in 5-10 years?

Yes I've heard about Redox, but I am under the impression that literally nothing runs on it except a couple of homemade apps like a calculator and a clock.

Are we ever going to realistically get a 100% Rust OS that takes advantage of Rust's guaranteed safety and supports/prefers Rust applications (real apps like web browsers, office applications, that popular application by Valve which automod hates, etc.)?
