Do the two overalp in their niches at all? You'd write a web server in Rust. But is there much effort put into Rust web frameworks?
It's just a weird comparison. PHP is competitive with JS, Python, Ruby and even Java. But Rust? That's C/C++/D territory. And Go is somewhere in between.
There is lots of effort by Rust devs, even if the libraries are not as mature or easy. I don't believe you meant to be disrespectful here. I think better a better words could be any of manpower, maturity, or time.
