Anyway, I'm actually glad that Go went down this path exactly because it allows us to look at the decision and see the costs. I'm very curious to see if we do hit that S curve, as another poster mentioned.
But it didn't die. And today there are more C++ jobs available than a decade ago.
In contrast, today there are some new languages that can actually be good contenders for C++. My personal favourite is Dlang.
Compilers, HPC, GPGPU, game engines, OS drivers, C++ is probaly the king of those domains.
Distributed computing, GUI frameworks, mobile apps, CNCF, other contenders rule the day.
This is also why I follow GraalVM since the days it used to be MaximeVM.
I love C++, but secure like the ALGOL linage it will never be, no matter how many fixes we throw at it, because that C copy-paste compatibility layer is never going to be thrown away.
Security must be applied end to end, and not pontual.
