6 of the 8 things you list are C or C++ which is, essentially, C with benefits--most of the code in C++ is identical to C except for interfaces--classes/inheritance/and all that. AI/ML are a small slice of the programming pie that is performed by people who wouldn't use C at the top level but you ignore the fact that, when speed is needed, C is used even there.

I'd go into this more but I don't feel like explaining these things to people ad nauseum. C is one of the most used languages around the world, in new projects, too, and nothing you've said changes that.
