No, you're missing what they said. True randomness can be delivered to a computer via a peripheral - an integrated circuit or some such device that can deliver true randomness is not that difficult.

Maybe I'm misreading it but I think the OP understands that.

If you feed that true randomness into a computer, what use is it? Will it impair the computer at the very tasks in which it excels?
