Per the article above, it=E2=80=99s starting small, with Rust usage in well-defined locations. This is not to say that we shouldn=E2=80=99t start organizing, but rather t= hat we still have a bit of time ahead. (During that time, interested readers can also take a stab at improving support for the Hurd, which relies on that revolutionary technology called =E2=80=9Caddress spaces=E2=80=9D to ensure Memory Safety=E2=84=A2 am= ong other things!)
