I understand and I see that Wedson also came up with some ideas
on how Rust can actually protect against some DoS type attacks.

But what attackers (who by the way are organized, well-funded and
pretty evil people) are creating and what is our biggest headache is
remote root exploits that open up systems to random code execution,
and that is why we have to take Rust to the enemy lines IMO, because
that is where it will deliver shock and awe.

The problem is not a few saboteurs in our factories in our homeland
but on the frontline with the enemy if you excuse the war metaphor.
I want to see Rust weaponized against the people who attack our
kernel.

Yours,
Linus Walleij
