The Rust ecosystem has lost sight of the forest for the trees in my opinion. I highly agree with Graydon's opinion in "Rust is mostly safety" [1] that it's raison d'être is memory safety and concurrency in the systems space. But strangely a significant amount of time is being put in to making it usable for other tasks. I think this has to do with the different cultures between C/C++ developers versus other developers, namely that developers coming from web development are younger and more used to jumping around to new languages and frameworks.
With it's borrowing semantics and steep learning curve, Rust will never gain significant market share in the world of web development. And why should it? Time to market matters more than speed. It's much easier to ramp up new hires on a C# or Go code base than on a Rust one. And the borrow checker will always create friction for people new to the language. As someone with a C++ background, it still took me over a month before I stopped fighting with the borrow checker and with lifetimes. I can't imagine how long it would take to get a completely new programmer up to speed.
