I agree with this, and yet, I love these new languages (esp. Rust) so I'd hate to halt progress. Instead, what I think we need is a solid cross platform native UI library targeting C (libui would be a candidate - before it lost momentum). It would then be a reasonable amount of work to create multi-language bindings. Instead we have things like wxWidgets/Qt that are a pain to create bindings for since it is written in C++. As proof this would accelerate things, notice how many languages have GTK bindings (C based).
