The Bitcoin protocol can be updated to also be secure against quantum computers.
The safety of cryptography is basically about using really big numbers. And if computers get fast enough to break the existing system, you just upgrade to use even bigger numbers that quantum computers can't break.
The protocol is actually fine already. It is the way people use the protocol that is the problem. They don't follow the recommendations in Satoshi's original document due mostly to ignorance about the reasons why it makes the recommendations it does.
