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 :)

'Actually, full disclosure, we really just rewrote a couple of components in Rust. Most of Magic Pocket (the distributed storage system) is still written in golang.'

Dropbox was (is?) Python. This is about Magic Pocket.

Yep, found detailed answer later there: ".. two components currently implemented in Rust are the code that runs on the storage boxes (we call this the OSD - Object Storage Device) and the "volume manager" processes which are the daemons that handle erasure coding for us and bulk data transfers.".

Makes sense to me.
