As for what consciousness actually is, I think the closest description is the summary of oneself. Meaning, all the computational power of the brain as a whole forms a person - a computational powerhouse with its own identity. That goes then to discussions where the "I", as in ego or oneself, ends. Is it at the limb, like a hand, or is it at an indivodual fallen hair or a dead skin flake? How about sperm or egg, is it still me?

Then we have the conundrum of people who get brain damage or some kind of degenerative brain desease, like Alzheimer. Where you can clearly see "them" fading away and you observe just a shell of a human being. So where is this "I" then? What defines it?

All of these are quite esoteric conversations more suitable for occasions where a lot of alcohol and few good friends are involved :)

Lenny Bruce joking as Tonto to the Lone Ranger:

Who is "we" white man?

The lede observation depends upon whether "we" can expect our science to ever produce an intelligible theory of mind.

The difficulty of producing a theory of mind makes the Imitation Game a compelling approach to setting expectations for AI.

And also portends of the hazard that we become so distracted by simulacra that we lose all bearing upon ourselves.

The primary difference being the enormity of the size of database, but the concept is identical.

To think 13 year old me had AI sitting in my attic.

We don't even have a universally accepted definition of intelligence.

The only universally agreed on artifact of intelligence that we have is the human brain. And we still don't have a conceptual model of how it works like we do with DNA replication.

Our society incentivizes selling out the mimicry of intelligence rather than actually learning its true nature.

I believe that there exists an element of human intelligence that AI will never be able to mimic due to limitations of silicon vs biological hardware.

I also believe that the people or beings that are truly in control of this world are well aware of this and want us to remain focused on dead-end technologies. Much like politics is focused on the same old dead-end discussions. They want to keep this world in a technological stasis for as long as they can.

The consciousness will have to wait for another time. But that one's likely to be extremely contentious and more of a philosophy question without practical impact.
