I love that it goes both ways, about plus and minus of both languages, including rewriting back into C++ when it made sense, and the side joke about rewriting existing CLI tools in Rust.
While C++ isn't perfect, has the warts of a 50 year's old language, and probably will never match Rust's safety, we would already be in a much better place if at least everyone used the tools at their disposal from the last 30 years.
While I would advise to use Rust for some security critical scenarios, there are many others where it is still getting there, and there are other requirements to take into account other than affine types.
