[ExI] You'd better sell your bitcoins

[John Clark]

Quantum computer expert Scott Aaronson has always been a vocal critic of
the excessive hype surrounding his subject, but just a few days ago he
wrote this:

*"I now think it’s a live possibility that we’ll have a fault-tolerant
quantum computer running Shor’s algorithm before the next US presidential
election. And I say that not only because of the possibility of the next US
presidential election getting cancelled, or preempted by runaway
superintelligence!"*

When we have a quantum computer big enough to run Shor's algorithm, bitcoin
becomes worthless. Aaronson then says this:

*"The two biggest known application areas for QC remain (a) quantum
simulation and (b) the breaking of public-key cryptography, just as they
were thirty years ago."*

*Quantum Computing, too much to handle* <https://scottaaronson.blog/>
