I count traumatic recollection of pain as a physical injury—it is a noticeable alteration to my behavior, encoded in physical matter.
This is a weird way to think about the word injury, and makes me think that you’re just considering the word “consciousness” in a similarly weird way.
But if you do insist, again this is easy, simply take a substance that introduces anterograde amnesia after administering the pain. No need to put your brain in a jar.
it’s a strong signal but there are enough people who think that this is just delusion to start a dozen more frontier ai companies if there’s a market gap
