That's true, and I don't mean to imply that I think it will replace Python/Ruby/etc. But I think Rust may find a sizeable niche as a high-performance, lower-level backend programming language for the web, sort of like Elixir. I've personally found the learning curve to be a lot smaller for web development than other projects because you don't have to learn everything at once; web development doesn't typically call for things like manual threading, so the borrow checker and other advanced features don't come up nearly as much or as early as they might for other codebases.
