Ok one bit of AWS runs on Rust.
C/C++ runs 99% of the the worlds software including OS's/browsers/GUI's/Compilers/Virtual machines/Games/Aircraft/Spacecraft etc etc etc.
"It'll be" same was said of Java
This is from November 2020, I’d expect them to use it even more by now:
> But we also use Rust to deliver services such as Amazon Simple Storage Service (Amazon S3), Amazon Elastic Compute Cloud (Amazon EC2), Amazon CloudFront, Amazon Route 53, and more. Recently we launched Bottlerocket, a Linux-based container operating system written in Rust. Our Amazon EC2 team uses Rust as the language of choice for new AWS Nitro System components, including sensitive applications such as Nitro Enclaves.

Mozilla wanted to push the boundaries of what's possible with a browser rendering engine and they felt like they couldn't do it safely with the existing languages, so they created their own. Doesn't that, alone, speak volumes for how useful Rust is?

Now you're being disingenuous. Rust is still so young compared to those languages! Not to mention that the industries best served by Rust move glacially slowly compared to, say, the web. I bet we'll see significantly more adoption of Rust in 10-15 years.
