The C++ I've learned and am trying to forget does a hell of a lot more than standardize the OOP boilerplate, give C++ a finger and it'll eat you and your family.
They will spend all of their time arguing about const &this and virtual destructor that instead of solving real problems until nobody really cares anymore.
The life so short, the language fucking impossible to learn.
If they feel they've got to improve their architecture, fine, do that. There's nothing magical in C++ that will make their code better, only more complex.
And about LLVM and the bad old days, that's not really what's happening.
What *is* happening is that the most commercial and proprietary company I know of is using it's resources to develop open source compiler technology.
