Imo the worst thing about starting out with C++ (which is much better with Rust), is the lack of credible package management/build system that allows you to just install packages.

This used to be even more true previously than today. Nowadays, there's stuff like vcpkg, and tons of resources, but I still wouldn't call it straightforward compared to something like nuget or cargo.

It tooke me more time to figure out CMake than entire other programming languages.

There's a weird cognitive bias where somehow people justify "I compiled this Hello World C++ project " as "C++ is easy" and yet "I wasn't able to understand how this optimized linear algebra library works" gets classed as "Rust is hard".

In reality it matters what you already know, and whether you want to understand deeply or are just interested in enough surface understanding to write software. There's a reason C++ has an entire book about its many, many types of initialization for example.
