Now you’re getting into garbage-collected abstraction though. Quite often you don’t have full control of the machine layer with C#.

This is not just saying “C++ is too complicated for me”. It’s also that even beyond managing precisely what memory holds, C++ is not intuitively designed, and deserves a successor fulfilling the same role. The reason game development often moved off C++ was that even as fast as it was, dozens of people would write failing or undiagnosable code in it purely because of the language design.
