Yes, but it seems the whole team (or all teams in large enterprise projects) must know a lot. Otherwise you still and up with a lot of hard to read, unsafe code

Yes, but it seems the whole team (or all teams in large enterprise projects) must know a lot. Otherwise you still and up with a lot of hard to read, unsafe code. If you start with a very large codebase of old C/C++ you might have to rewrite large parts of it to reap the benefits and in that case you might want to look into other languages as alternatives. I agree that for a green field project with very good developers C++ 14 looks nice.
