Yes, sadly; and this is because programming languages, like spoken languages, live and die by their community. And it's harder to cross-pollinate programming languages since all changes must be backwards-compatible with existing source text. Language interop is usually terrible. You can't easily bring just a bit of Inform into an application.

This is very slowly improving with the popularity of compile-to-llvm, compile-to-CLR, and compile-to-JS as intermediate targets.

The other factor in faddishness is ahistoricity; the most energetic and community-orientated people are young, but interested in building their own new wheels while overthrowing the old wheel order.
