I've seen this bouncing around since the early 90s, with New Agey people like Danah Zohar, and probably predates even that. There never seemed to be a whole lot to it; not much more than "well, consciousness is weird, and quantum is weird, therefore consciousness is quantum". Or maybe "well, quantum is trendy, and I'd like to make a buck, therefore..."

I'm unsure what to make of the post you're replying to, but the idea that there's a connexion between consciousness and quantum phenomena isn't just a New Age idea. Eugene Wigner wasn't New Agey, and he wrote Remarks on the Mind-Body Question, suggesting that wave function collapse only occurs when the consciousness of an an observer becomes aware of the result of a measurement, not the measuring apparatus, which is entangled with whatever is being measured, records it.

For me the most plausible argument for "quantum consciousness" was made by Roger Penrose. I still don't believe it; we can demonstrate wavefunction collapse using experiments like the delayed-choice quantum eraser without anything conscious being involved (unless you believe in retrocausality or the cosmic conspiracy theory, or in panpsychism, which is really no weirder than the quantum consciousness ideas and also quite fun to contemplate).

It seems like you disqualify everything that doesn’t talk back (LLMs then?). By my account a stone is dormant quantum consciousness and living systems merely animate this. Awareness and sense of self are manifestations of biotechnology.

FWIW the only place I EVER see the phrase "citation needed" is on HN. That's not a good or a bad thing: it's simply an observation.

Pretty sure it originated with the Wikipedia annotation. See e.g. https://xkcd.com/285/ from 2007.

With apologies to the above post if I'm wrong, I've seen it as a polite way of saying, "bullshit."

Only if they can't provide a reliable citation.
