Reality check: no one has ever built a quantum computer with qubits lasting more than a tiny fraction of a second, and quite possibly they never will.

I think what I find so amusing about the original post is that the first QC experiments I was involved in, 15 years ago, had a 1.3Hz coupling that was used to perform gates (it was nuclear spins).

It’s bizarre to me to double down on insisting there are no long lived qubits, but miss the obvious -valid- criticism that gate time to coherence time is a more relevant measure of computational capacity.
