Sleep is weird. People object to the transhumanist idea of "uploading your brain" into a computer, which I think you are hinting at with "encode your consciousness" because there will be a discontinuity when the wet brain turns off and the electronic brain turns on. But we lose consciousness every evening and come to in the morning. What kind of continuity do we have now?the headlights of my school bus rounding a sharp corner early in the morning. It was dark, and all that was illuminated were cedar tree branches.
This image stuck with me since first reading it earlier today. Maybe it will stick longer.
Yeah, I've been thinking a lot about this lately, which has entirely too much to do with having seen Ex Machina and Chappie within the last couple of weeks. I would contend that today's humans (and all other animals that sleep) have full "continuity of consciousness" between the sleep to awakeness transition, or vice versa. We're not fully alert while asleep, but still certainly conscious, and the processes in the brain just change between the two differing states. The moment of discontinuity when uploading/encoding a consciousness into a new form may serve as barrier that we can never cross. If you simply make a copy of yourself and boot it up (so as to circumvent "pulling the plug" on your wet brain), all you've done is clone yourself. Here's an even better mindfuck; let's say we think we've been successfully transferring wetware to hardware. How can I guarantee that it isn't just the clone saying "Yeah, I made it into the computer just fine, thanks!", and that you have actually died, but the copy you made of yourself shortly before your death was booted up, and behaves just as you would? Maybe if we copied someone without their knowledge, killed them, and then booted up their file? Oh god, this is fun, but is, at present, unknowable. Another aside: Although I've never heard it put into these terms, believers in reincarnation seem to subscribe to some sort of "conservation of consciousness" theory. Again, unknowable, at least this side of death (and very possibly the other). I've only seen a little bit of it, truthfully. Definitely have a dream journal laying around here somewhere that only has maybe 10 entries. Had a few lucid dreams before, but I always end up either choosing to fly or have sex with a woman not too dissimilar from Mouse's "woman in red" in the Matrix. Pretty boring, considering the endless possibilities. Edit: Ah, and I managed to achieve some form of sleep paralysis back in high school. I never slept at night, and fell asleep during class with my head in my arms on my desk. My mind would often wake up, receiving audio, conscious of my breathing, but was unable to conduct any physical motion, including opening my eyes, yelling to pull myself out of this purgatory state, punch myself in the head, anything. Sleep paralysis is terrifying, it's true, especially the first few times. Ever seen Altered States? Heh, interesting flick. I do find it fascinating that humans are reportedly unable to cope with total silence. I'd love to get in an isolation tank and see what happens.Sleep is weird.

This seems to require a rewrite of the usual dictionary understanding of conscious and unconscious. Sleep is a deeply altered state. I can still perceive stimuli, so that a loud noise or shake will wake me up, but I am not aware of any stimuli, or at least I don't remember them long. It seems like awareness is the main difference. I don't know I am sleeping; it is much like being dead. My friend Barış told me about his idea of a workaround the night before I had my lucid dream. He suggested that you could transfer the mind gradually. As you activate the neural mappings in the new substrate, you keep them wired to the old brain. You turn off the old nodes one by one as you turn on their new copies. The conscious person would always have a complete, intact mind, and there be no awkward moments of non-existence or duplicate existence. I didn't think it fair to criticize this plan on technological grounds, since there's no telling what will eventually be possible, but I thought of a laws-of-physics objection: No matter how near you have the new mind matter, there will be some unavoidable lag in signals going back and forth to the old brain. Assuming that timing is critical in neural messaging, I conclude that the mind will become hopelessly jumbled and confused while it is divided across two locations. The process would be so disruptive that continuity of experience would be impossible. Added to my queue. I would like to give it a try too, but I wouldn't expect it to be so intolerable: "a mix of deep relaxation and temporal disorientation" sounds reasonable for anyone spending an hour wide awake in a dark room.We're not fully alert while asleep, but still certainly conscious
