AI has made me wonder a lot lately about what it is that actually creates conscious experience, what is the actual physical mechanism that produces 'experience' (or is there a single valid mechanism, or rather just some property that can be expressed many ways). The more I think about it, the more I realize I have no fucking clue, and the more interested in the question I get.

This is speculation but maybe in the recurrent coupling between neuronal activity and the brain’s endogenous EM fields: neurons generate the field, the field ephaptically influences neurons, that closed loop may provide the physical integration associated with consciousness. A very active area of research so we will find out a lot more in the coming years.
