why we can’t follow project kronos’ blueprint
Project Kronos, the short fake documentary by visual effects artist Hasraf ‘HaZ’ Dulull about first contact and the possible origins of interplanetary travel by humans in the relatively near future, recently got plenty of attention on the web. And it should have. It’s a well done piece of work, its premise is developed enough to keep you glued to the screen, and its pacing and storyline are open ended and somewhat disturbing enough to provoke a lot of speculation. As a piece of art, this is really, really good. But before anyone gets ideas about sending our artificially reanimated brains in spherical vessels to roam the cosmos in a dream-like state, I’m afraid that a skeptic will need to step in to do some fact checking on the science regardless of how well Project Kronos was put together. Considering that I’m in one of the key fields involved, it may as well be me, so let’s unpickle some flying cosmic brains and figure out whether you really want to analyze fuzzy dreams on your way to meet an alien intelligence trying to summon you to the stars.
Believe it or not, mapping the neurons responsible in remembering what someone saw could be done, and there’s been some success in trying to see what another person has seen by looking through his memories. With enough time and more accurate devices, it’s not implausible to get much better resolution, maybe even as good as some of the fuzzy images of the brain implanted into the Kronos probe. But then again, you’re spending hundreds of millions, if not billions to get to interstellar space. Don’t you want extremely powerful high resolution images taken with crystal clarity so scientists can study what the probe gleams on flyby? Don’t you want a sensor array to measure everything from the solar wind to atmosphere of the gas giants’ moons? The film’s very ambitious space agency basically decided to take a shortcut to nearly human equivalent AI with an actual human brain, then launched it into deep space bereft of the tools to make the probe a source of good data for planetary scientists, focusing instead of establishing first contact based on the idea that a human brain would handle aliens better than a recording. But would it?
One of the more disconcerting things for me in the documentary is the notion of the brain kept alive after the person using is has presumably died of natural causes. Now, as someone who’d happily donate his body to science after I’m done using it, on the one hand, I would welcome the opportunity of being essentially resurrected as a space probe. In fact, on the surface, it sounds like one of my wildest dreams come true. To be brought back to life in some form and launched to travel the stars for eons on end. The concept is poetic, really. But the reality? Not so much. It would be the most extreme kind of sensory deprivation you could imagine. Yes, you could travel the cosmos and see planets no one has even seen before, but for the vast majority of the trip, you’d be surrounded by silent blackness. No friends, no family, very little interaction from Earth, and most of said interaction would be one way. Your thoughts and memories would be decoded and played back like a movie, complete with images of the life you once lead. What you have to look forward to is eons of solitary confinement in a completely alien environment.
Of course this is presuming that your brain will still be usable after death. Unlike the machine, it will deteriorate. Over time its functions will degrade, memories would be difficult to keep, and the probe will grow less and less reliable. Add this to the isolation it will experience and any aliens in range of a Kronos orb will more than likely be trying to make contact with an entity suffering from mental illness and with rapidly deteriorating cognitive abilities. At this point, a recording would be much more preferable. Now, you might wonder if the brain in a Kronos probe would actually live in any real sense. After all, it is just being zapped with a little electricity and given some nutrients so it can function but it’s not really embodied anymore and kept in a dream-like state. The film is not really clear on this point, oscillating between the scientists treating the brain as a substrate, and indicating that it would be capable of an emotional response, meaning that it may be sort of alive in a conventional sense. Maybe this is why the Human 2.0 project meant to respond to the alien attempt at first contact uses a fleet of probes. Maybe they’ll keep each other sane.
Still, note that first contact happens after aliens hack a human brain in robot form. That’s a very disconcerting feat. It means that the extraterrestrial life form either managed to figure out binary protocols for our electronics and how they map to analog buzz produced by our neurons, or had a machine capable of doing that. More than likely, they’ve either done it before or developed an absolutely amazing grasp on how to decipher brain machine interfaces in other species. They’d have to basically torture the brain in Kronos to figure this out from scratch, not on purpose, but they would more or less have to wire into the orb and zap the brain to see what happens so the inference map for how it works could be built. Does sending a hundred more Kronos probes to the coordinates they provided seem like a good idea in this light? Certainly not to me. Seems a tad dangerous to put it mildly. Sure it’s first contact, but with what and why? I could imagine this encounter suddenly diverting trillions around the world into building a heavily armed space fleet just in case, should the memories of the Kronos brain give the aliens too much information.
But all this aside, I can understand what Project Kronos was trying to show. Humans, as we are today, are more or less marooned on Earth. We’re not ready to live in deep space until we start to change ourselves through genetic engineering and significant augmentation, until we defeat aging as we know it and learn how to encase our bodies in materials that will keep us save from radiation and let us stand on other worlds without worrying about toxic chemicals, radiation, and the bone, joint, and muscle damage from changing gravities. The odds of us being brains in tiny orbs floating through the vastness of space are non-zero, especially if bean counters have their way with the future of space travel, but it’s not the best way to explore the final frontier. No, the best way forward for us is roaming space stations, vast interstellar ships, and cyborg bodies. It’s our need to be social, our embodiment, and our sense of community and adventure that define us, and if we want to boldly go into interstellar space, we need to carry them with us. That and a lot of weapons in case random aliens start giving us trouble by trying to hack into our brains…
