Yes, but also it's not looking good because theoretically this exploit could be applied over more bits with access to more qubits right? So it is only a matter of someone getting their hands on enough quantum computing cores.
But it was already theorized that this could happen, RSA had been considered unsuitable for a while now.
Exactly, this method scales with the size of the quantum computer, so we could see RSA broken within a decade. And this technique could apply to a lot of other existing algorithms. The key part to keep in mind is that there is a lot of encrypted data that has been collected already that people simply had no way to decrypt. So, there are retroactive consequences here as well.
