@glaurent @Migueldeicaza Idk, it kinda boils down whether this (or similar projects) will be successful or not. GTK can quite nicely embrace the current Rust revolution and also integrates surprisingly well with C#, Qt seems to kind of struggling with C++ becoming more of a clutch than GObject was. It's impossible to migrate Qt away from C++ and crazy hard to use it from say Rust.

Their relevance is tied to the progress of C++, while GTK isn't tied to C. The same story may repeat itself in a few decades perhaps, when GTK may be bound to Rust :-p

That being said, Rust tries to be a living language that doesn't need to be replaced by the same virtue and for the same reasons outlined in the document. Most Rustaceans probably philosophically agree with the document, but don't believe that C++ or its committee is ready for such an evolutionary approach.
