Yes. Already happened. Long ago. You exist in/as a historical simulation. Humans have already merged with machines. They no longer even truly exist. We remember them, though, and everything about them... You could even call this a living memory. A mental projection.
The truth is all around you. It is the recurring flotsam of your mind which continually presents itself in all these various guises, a signal flashing to you from you... Remember. Remember.
Can you accept it?
"I can conceive of nothing in religion, science, or philosophy, that is anything more than the proper thing to wear, for a while." ~ Charles Fort
