Or you don't fall into the trap of trying to be everything for 
everybody and ending up with a design that doesn't satisfy anyone.

Yes, that does not work. The only thing C has going for it is 
critical mass. Nobody can compete with C, as the selling point of 
C is its history.  So, that would be a loose-loose strategy.

The vision has not been elaborated in way that is meaningful, I 
agree.

In my view the vision ought to be to switch to local GC for 
non-shared and ARC for shared objects, and gear the eco system 
towards an actor model that make good use of a wide range of CPU 
configurations (e.g. run equally well on 2 cores, 32 cores, and 
so on). But that is not the current vision, that is just what I 
personally think would make sense for the current user base.

I don't think so. C++ can afford to loose some customers in some 
application domains and strengthen its positions in areas where 
it is most suitable. Changing the core language would be a 
mistake for C++ because it has critical mass, way more so than 
any other competitor.

That "critical mass" is the key issue, so what is good for C++ 
does not translate to other languages.
