I didn't remember ever seeing you excited about Rust :-) In

I don't think Rust has a chance against D. -- Andrei
The real question is which language, from all that want to
replace C++, will eventually get a place at an OS vendors SDK.
So far, the winning ones seem to be Swift on Apple side, and
.NET Native-C++/CLX on Microsoft side (who knows what are they
doing with M#).
Maybe someone in the commercial UNIX (FOSS is too bound with
C), real time or embedded OS space?

Interop, interop, interop. Walter and Andrei are right when they
talk about the importance of C++ interop - not only do you get to
leverage those libraries, but it reduces the barrier to entry for
D in more environments.
Swift will never be more important than Objective C was - which
is to say it'll be the main development language on Apple
products and probably nothing else. That has real value, but the
limits on it are pretty hard and fast (which says more about
Apple than the language itself.)
.NET suffers a similar problem in spite of the community's best
efforts with Mono - it'll always be a distant 2nd (or 5th or
20th) on other platforms. And on Windows, C++ won't get
supplanted by .NET absent a sea-change in the mindset of the
Windows OS group - which is notoriously resistant to change (and
they have a colossal existing code base which isn't likely to
benefit from the kind of inflection point Apple had moving to a
BSD and porting/rewriting scads of code.)
So C/C++ is it for universal languages, really (outside of the
web server space, where you have a large Java deployment.) I
don't think D needs to be the next .NET (of any flavor) or the
next Swift, and I don't see as it is being positioned that way
either - the target to me is clearly C/C++. It doesn't need to
compete with languages that have lesser universality, though it
should (and does) borrow the good ideas from those languages.
I don't think D needs to look at *replacing* C++ in the near or
mid term either - it still needs to convince people it deserves a
place at the table. And the easiest way to do that is to get
this C++ interop story really nailed down, and make sure D's
warts are smaller than C++'s. And, of course, the GC strawman
that native programmers always claim is more important than it
really is. I like the threads going on currently about ARC and
related technologies - there's a real chance to innovate here.
