That depends; do you mean that it has to be written in the next ten years and then later becomes widely used, or that it has to become widely used in the next ten years? If the former, I'd say maybe if Redox becomes mature enough to be widely used maybe a decade or so down the line (with "widely used" meaning "used as much as at least one of the major BSDs", since those are what are being discussed in the PDF), and if the latter, I'd say almost definitely not (and this is coming from a huge Rust fanatic)
