Saying that it is possible is an unproven and unfalsifiable claim. Everyone involved in running the QC circus has huge incentives.
- There are strong reasons to believe that it is NOT possible.
- There are strong reasons to believe that, if it is possible, it may be very far in the future.
- There are strong reasons to believe the people raising the alarm are either being fooled or have strong incentives to raise a false alarm.
- Doing anything about it seriously damages Bitcoin and freedom tech in general
- If they ever actually do crack the first key, we will have plenty of time to adapt before meaningful QC threat is economically viable
- FUD also hurts Bitcoin and freedom tech
Conclusion: Do not touch the code, just shut down FUD to protect freedom
We fight battles like this over and over.
