I would say this is largely true. C++ is incredibly fun and incredibly hard to wrangle. I think it's one of the most interesting ecosystems out there and you would have to do a lot of convincing to get me to start a new project in it. Everybody says they're going to be more disciplined this time, but after enough time, they remember the not-so-fun parts of the language. I'm not one of those freaks that has a fanatical drive to rewrite existing C++ software in Rust, but I do think it's something that's best avoided if you can help it.
