"The number one problem Rust has now is that it’s overall not significantly better than C++"

This might be true for your specific use cases, but I've worked on reasonably large projects in both Rust and C++ and the fact that I don't have to chase various issues related to use-after-free, returning local variables, dealing with external libraries or general metaprogramming is definitely causing me to mark Rust as significantly better.

As always, if you're a C++ expert you'll bound to disagree, YMMV etc.
