Has quantum advantage been achieved?

Dominik Hangleiter writes on his blog:

Recently, I gave a couple of perspective talks on quantum advantage, one at the annual retreat of the CIQC and one at a recent KITP programme. I started off by polling the audience on who believed quantum advantage had been achieved. Just this one, simple question.

The audience was mostly experimental and theoretical physicists with a few CS theory folks sprinkled in. I was sure that these audiences would be overwhelmingly convinced of the successful demonstration of quantum advantage. After all, more than half a decade has passed since ...

I could not have been more wrong.

In both talks, less than half of the people in the audience thought that quantum advantage had been achieved.

No, quantum supremacy has not been achieved, if most experts are not convinced. The whole was to do a public demonstration that convinces everyone that quantum computers are possible.
