C++ is also the standard in game dev. You may see some C# here and there, but most engines, public available or otherwise, are built on C++.

If it is a AAA game, I can assure you it is most likely made with C++.

Most of the embedded world uses those.

Embedded systems developer here. If you’re programming on ARM or one of the other big microcontrollers there aren’t many well supported options. ARM’s official Keil compiler and libraries are C and C++ and I see no official movement to change that.

They have literally decades in building those tools.

Microsoft’s multithreaded OS ThreadX is C code. They just bought it for a large undisclosed amount in 2018. It ain’t going anywhere soon.

AWS’s FreeRTOS is C. Not going anywhere.

Embedded development toolchains are very slow to change.

Basically, C runs the modern world. WiFi, MacOS, Windows, Linux, and so much more

A large chunk of not most of robotic development is C and C++. Since working with a mixture of hardware, software, and even performance software here comes C and C++.
