It's a reasonable spiel if you believe QC is an imminent threat.

I found the comparison to Y2K humorous, as Y2K turned out to be a nothingburger.

I propose that QC should be ignored until any lab can legitimately show "qbits" doing any real mathematical computation (without cheating).

Last time I checked, one claimed they could factor the number 15, but they cheated.

15 = 3 * 5 is a very long way from brute forcing SHA 256.
