Speaking for Ruby/PHP web apps. Go is not quite as fast as Rust, but much easier to pickup since it has a simple syntax and manages memory for you. I would save Rust (or C) for the optimization phase since finding developers is harder. Go is so good that huge companies like sendgrid, cloudflare and google never move past it. Rust is great for hardware and embedded devices where memory management really, really counts.
