I don't think they can afford to provide any automatic memory 
management solutions, since everyone is basically looking for an 
excuse to hate on them

At best, I can imagine them enshrining C++'s `make_shared`, 
`shared/unique_ptr`, etc constructs for better 
optimisations/error reporting/airtight implementations, so that 
nobody can accuse them of introducing performance detrimental 
things like GC(notwithstanding the fact that RC is also a GC 
technique)

I genuinely think this thing might be successful, people disliked 
Go so much, yet look where it is today: the entire foundation of 
the cloud is built on it; Dart had nothing to it's name, now it's 
fighting JavaScript for supremacy as the most cross-platform 
friendly language; I feel Carbon will be a similar success as 
well, if they really get C++ interop, tooling, and job 
opportunities right
