Wow. This sounds intense and interesting. However I will stick to C++ but it is great to see power languages up and ready for new generations of hardware, software and people.
Once nice thing about Fortran's evolution is that when you lag behind the bleeding edge, you make fewer mistakes. If you like C++ that's great; you might notice that everyone else doesn't agree that it's the future.
Funny that you should mention it. To me it looks like web development is mostly driven by fashion rather then practical choices. Also I suspect that unless something radically good comes out (I do not consider Rust, Go and likes to be the case) C and C++ will stay very active, including new development. I actually do hope that this happens but so far no real candidate.
