Recurring claims

BIP-361 proposes freezing vulnerable Bitcoin wallets to protect against quantum attacks, but it risks locking away coins including Satoshi's holdings.
Adam Back advocates for optional, opt-in quantum-resistant upgrades rather than forced freezing of wallets.
Current quantum technology is not an immediate threat to Bitcoin, but future advances could compromise wallet security if upgrades are not made.
