Go and D are evolutionary steps. Is the race won by having the properties of better than C/Cpp observability, safety, performance, quality of life lib/tooling that leverages AI for debug and deeply sophisticated, technically aesthetic rapid prototyping exploring the solution space styled after DeepMind and mathematical knots?
C and C++ are classics that Java and .NET tried to replace.
Well, for many use cases they did replace C++. Not passing a value judgement here, just observing that most professional programmers wouldn't resort to C++ for most tasks.
