I believe that future D, or a non-backward-compatible successor, 
will be more than competitive across the entirety of the 
programming landscape.  Pay-as-you-go + ridiculously good 
metaprogramming capabiity == master-of-nearly-all.

D may not be able to get there, better-than-Rust safety and 
opt-in-ultra-low-latency GC are two features, among others, where 
the future looks a little iffy, but D surely points the way.

Counter examples showing how it is impossible to advance D to 
become master-of-nearly-all are requested.  Counter examples 
showing how it is impossible for any language to be 
master-of-nearly-all are also requested.
