What nobody seems to bring up is the complete lack of a proof of concept attack on something easier to Crack. An 8bit DSA analogon cracked by a 48 logical Qbits machine could be a useful canary. PoW!

All the QC arguments I have heard over the years are fear based with minimal backup, because spooky quantum.

48 logical qubits don’t exist yet - as pointed out in the video.

My main point: We need a canary - an intentionally weak, 8-bit ECDSA - something that small (available) quantum computers can actually crack. Otherwise, quantum cryptographers will keep feeding us suckers the FUD we deserve. Give them a real target or shut them down. I've seen this grift from the inside for years.
