I love D, learned it back in high school, but unfortunately it just seems like D is one of those great languages that just isn't going to take off. It just doesn't have a big enough champion to bootstrap a thriving large community that would make more people want to learn it and more companies adopt it.

On its technical merits, one of the best languages out there. It gives you insane performance but is so much easier to learn and write than C++ or Rust.
