The trouble with quantum supremacy results is they disappear as soon as you observe them (carefully).
Sorry for that, but seriously, I'd treat this kind of claim like any other putative breakthrough (room-temperature superconductors spring to mind), until it's independently verified it's worthless. The punishment for crying wolf is minimal and by the time you're shown to be bullshitting the headlines have moved on.
The other method, of course, is to just obsessively check Scott Aaronson's blog.
