C is still highly used for low-level system software development: OS stuff like drivers, libraries, compilers, databases, software that runs in specialized small hardware, etc. C++ is for those slightly-higher abstractions that still require a lot of performance, like video-games and some of the former. Some stuff is getting very slowly replaced by Rust, but it will still take a long time for Rust to corrode the C/C++ market share in the lowest level stuff.
To me, Xbox is that video-game you get when you ask for a Playstation and your parents don't understand video-games. Their versioning scheme even helps make sure the parents fail to purchase the latest generation.
