The part about what I think consciousness actually is is just fun speculation by my part, not to be taken as an objective argument, just an interesting suggestion.
I think you can absolutely rule out consciousness as an external entity. It goes back to how I said consciousness isn’t special. It can’t be external without being “supernatural” (I use supernatural not to label the unexplained, but the made up). For consciousness to be an external entity such as the supernatural soul it would require that there is more to the human brain, in fact any brain, than the particular arrangement of molecules. I challenge any such “special” interpretation because it is completely unfounded and wouldn’t make sense in the context of evolution; consciousness under evolution must emerge as the further development of the brain. How could such a development be aided by the materialization of an outside entity appended to the brain? There was a point in our development where we did not have consciousness, and then there was a point where we did (obviously the line is probably much blurrier than that, one could simply pick a point on either side of the grey to make this claim). The only difference between those two points is mutation and natural selection.
This thread got derailed from the very start, it was meant to be about stupid inventions, not stupid ideas. Lets just enjoy where it goes.
