Define most here a little bit more. I would imaging most people using it are hobbyists/students and, in that case, I think you're right.

But most people using it in industry fall into two camps:

1. using it because the project is old enough that C++ was a reasonable default when the project started. You may also be right here

2. using it because performance is absolutely critical to the application, here I would actually imagine you're wrong. noexcept removes a ton of stack-unwinding code, and you can absolutely get a significant performance boost out of it. It would be weird if they didn't pull this lever, given the perf boost and that errors as values is also a fairly reasonable way to handle problem

In the second category, google famously had a "no exceptions" rule at one point (could still be in effect, I have no knowlegde of google)
