"faster than C" almost always boils down to different designs, implementations, algorithms, etc.

Perhaps it is faster than already-existing implementations, sure, but not "faster than C", and it is odd to make such claims.

One big part I've noticed when working in rust is that, because the compilation and analysis checks you're given are so much stronger than in C or C++, and because the ecosystem of crates is so easy to make use of, I'll generally be able to make use of more advanced algorithms and methods.

I'm currently working with ~150 dependencies in my current project which I know would be a major hurdle in previous C or C++ projects.

Everything you said is correct of course, but the idea of auditing 150 dependencies makes me feel ill. It's essentially impossible for a single person.

This is why sharing code is so important; it doesn't fall on one person, but instead, on the overall community.

For example, cargo-vet and cargo-crev allow you to rely on others you trust to help audit dependencies.

Oh, absolutely. Software cannot scale without trust. No single person is capable of auditing their browser or operating system either.

The effort is _roughly_ proportional - if you need to parse JSON in either language you can write it yourself or use an existing library. Both of those are the same amount of work in c++ and rust.
