After working with a 300,000 LoC code base of PHP I would gladly rewrite Facebook in Rust. It allows effortless atomic commits. When I build something I make an MVP of a first version, refactor, make an MVP of the next version, refactor, and so on. Rust lets me make sure my code still works through refactors and code changes. With PHP I could easily break something that would only cause an error when that code actually runs. That's right, there is no sanity check at all until the parser reads that code.
