Yes, but at least it was a real thing with a serious proposal behind. Even if Carbon ships, what value would it give in 2029 or whenever it is in a world where writing rust or heck even C++ is now way easier and foolproof (as long as you know where to guide an LLM)
The Carbon team has always been the first one to assert this is for Google internal purpose first and formost, everyone else should go to Rust, Java, Go, C#, Swift,... whatever fits their workloads.
It has been the social media that has given Carbon a roadmap that the team never communicated.
As for Cpp2, it was yet another C++ wannabe replacement, sold as if it wasn't, because the chair of ISO C++ at the time, naturally could not be seen as yet another one coming up with C++ wannabe replacements as well.
