Hi,
You might consider reading a lot of the messages in the bitcoin dev group in addition to here:
https://groups.google.com/g/bitcoindevThis seems apropos from yesterday about why quantum protections are important to consider now:
Note that such a death spiral and the incentives for a soft fork are possible prior to quantum attacks on Bitcoin. Merely the threat of quantum attacks and the widespread belief that Bitcoin will not freeze unspendable coins and thereby inflate the supply of spendable bitcoin.
In short, while I don't think the 80k bitcoin movement has anything to do with quantum, the fear that something similar could happen in 5, 10, 20, 30 years with huge uncertainty is the issue over time.
