>> Spend the next 5 years learning the ins and outs of C++, [..,] Spend a single month learning Rust. Play with it for another month or even two just to be sure. Hopefully after the 3rd month, they'll be 100% certain that their code won't break [...] Rust gives me the confidence to "compile once, run safe everywhere".

See, this is exactly the fallacy that I am criticizing. I think the belief that "C++ is too hard to learn but one could become a good systems programmer in rust in a few months" is - frankly - misguided. I think that in order to become a good systems programmer in rust, you _will_ have to know all of your systems basics (i.e. you should already be able to code in C for starters) and then some more. But sadly this seems to be the spin that their marketing is pushing also.

Personally, I found practical rust (that interfaces with actual system libraries - think openssl) to be more or less on par with good C++11 with RAII memory and ressource management in terms of practical memory safety. Having somebody writing rust code without a basic understanding of things like ressource management and threading is just as bad as having them writing "unsafe" C(++) code.

I hope I'm not feeding the trolls here.
