Provided their assumpions are correct.
Clearly quibit coherence time is a critical parameter here.
What happens if that increases 10x? 1000x? 1000 000x? And yes IIRC a small number of physical processes have improved by that much over their initial versions.
Now how many ASICs are you using? 1? A board full? A server room full?
It was only when the EFF developed a DES cracker ASIC and IIRC about 8 of them dropped the worst case crack time to less than 1/2 a week at 20MHz, when the NSA finally admitted a 50 bit cypher was insecure.
I don't think people should stop worrying just yet.
And that's before the kidnapping and wrench option is considered.
