We can't afford to wait for it to break. CRQC would kill Bitcoin if it was real today. An attacker could manage to take most bitcoins while causing panick and a fee event that would generate weeks of mempool backlog, exposing even more coins.

QC scaling big enough to break a Bitcoin key is not physically possible. The "fix" would be extraordinarily damaging to Bitcoin.
40 years of QC research has only proven that the Lindblad master equation holds.
Max is 170 qbits for one hour. Breaking s key (shor) requires ~2000 for hours.
It's pure FUD and QC is a shitcoin.
