Dropbox started out in Go and rewrote in Rust.This is actually very good news. It means there are at least some big companies that do measure technical impact of used programming languages instead of going with the trend :) And that they are not scared to change the decision if it proves inapplicable.Bad news the new choice is Rust and not D :) Though I can totally see why based on mentioned requirements.
In next iteration they will migrate from Rust to D :)
