I have been waiting for a good story how to sell D for adoption, since Andrei published his book.

Most of the stuff that interested me back in 2007, is now available across in C#, F#, JVM languages, Swift, OCaml, Haskell, with a better ecosystem and IDE tooling.

And then there is C++26 and Rust 2024.

You achieved a lot as language designer, but it is still not clear how the community would keep the language going forward in lets say 10 years from now.
