Don't most large products have teams working on performance? With a VM-based language like Ruby, speeding up the VM is a sound strategy because it works across all of your applications. There are teams embedded in corporations working on the JVM, the Python VM, the PHP VM, and so on (sometimes brand new VM implementations). There are teams working on improving performance of the standard library and compiler in C, C++, Rust, and Go. There are teams working improving performance of applications in all of those languages. Sure, if you're a startup and you can't afford it, you probably shouldn't be spending time speeding up your language. But, you're also unlikely to experience performance issues under your lighter load that can't be attributed to your application.
