I agree it's too tough to define. So I'm just basing this off of vibes. One of my closest friends is a really good C++ programmer, so that's where I'm coming from. I'm not a C++ programmer at all.

I think the C++ standard might be the biggest. Like, just the amount of compiler passes it does and what means when is kind of insane. I shouldn't even have seen that in my life, yet I did. I guess that's what friends are for :')

But the ecosystem of C++ seems quite small compared to others as C++ programmers want to build stuff themselves.

So it depends if you just look at the standard versus the ecosystem.
