GC is the right memory management strategy for a lot of use cases.
But there is many more where it isn't the right one.

D however is naturally more useful and hence successful in the second 
set of cases (see Weka.IO and Sociomantic as examples).

And no, you can use classes without the GC pretty easily. Its just that 
structs are even easier still and we do love counting cpu cycles.
