Hmmm, this lies quite far from my area of expertise. Therefore, I won't be able to comment a lot. Sorry.

As a physicist, I tend to be very cautious with concepts like consciousness, especially when they are framed in ways that seem to conflict with well-tested principles such as causality or relativity. Claims involving super-luminal information transfer, in particular, would require solid and reproducible evidence as they would fundamentally challenge a large body of established results. That being said, I do find work like Michael Levin’s (which I do not know much so that I had to check online) interesting. From what I have seen, it appears to remain grounded in measurable mechanisms even if some interpretations may go further than what the data strictly support.

For me, at the end the key issue is how to clearly define what we mean by 'consciousness' and how to design experiments that can isolate it from any other physical processes.
