Will Quantum kill Bitcoin?

just recorded a podcast with quantum computing legend scott aaronson and cryptographer 
@drakefjustin
 

7 takeaways:

1) quantum computers that break current bitcoin & ethereum cryptography are simply a matter of when not if - it's now just a matter of engineering and scale

2) if quantum computers with millions of qubits happened overnight bitcoin & ethereum would be wrecked - attackers could steal trillions in assets and generally god mode both chains - fortunately we still have years until this is possible

3) but when that day comes bitcoin is in for a rough ride - not on the tech layer but on the social - "the community" will have to make a call on bitcoin property rights - no clear path to dealing with the 1 to 4m btc that can be stolen by the quantum attacks (5-20% of all bitcoin lost/inactive cannot be upgraded) - does bitcoin let this happen or breach its immutable property rights - which is least bad for number go up? do we fork?

Quantum computing will eventually pose a threat to Bitcoin and Ethereum, but it's not a today problem years remain to innovate and adapt.
