C++ and D aren't the kind of languages that get hype because they're the kind of languages that see serious use right away. If you're deep in the trenches writing C++ and/or D code, you don't have the time or the need to generate hype. You're getting actual work done. Things are different for languages like Ruby or Go. These were used more as flights of fancy for certain people, many of whom were not getting real work done. So they had time to write lengthy blog articles, make YouTube videos, host conferences, and write really weird and absurd tutorials. These are the kinds of things that generate hype. Hype is a product of everything but code; actual code is the anti-hype.
