    I thought Cat Brain was a mind-blowingly impressive follow-on to the Blue Brain simulator. Blue Brain simulates a single neocortical column. It's only 10,000 neurons, but its model "consists of 10,000 3D digitizations of real neurons that are populated with model ion channels constrained by the genetic makeup of over 200 different types of neurons." It simulate the actual chemistry of neurons and as such is the only biologically accurate simulation (of a tiny part of a juvenile rat brain).

    Cat Brain sounds massively better with 1.6 billion neurons signalling each other through 9 trillion connections. But it only works if modelling neurons as simple "points" that signal each other with single values is a productive simplification of brain chemistry. As Blue Brain guy says "There is no qualified neuroscientist on the planet that would agree that this is even close to a cat's brain."

    Meanwhile, scientists are puzzled by the dog brain simulator, unsure of whether they've created something endearing or stupid.

    We think dogs are smart because we can teach them to perform tricks to satisfy our whims. Cats think the same thing about people.

    Also, true story: I recently witnessed a dog, who freaks out at everything that walks past her house, being let out the front door for a quick run around the neighborhood. She immediately turned left and ran a couple houses away to relieve herself. Not thirty feet away in the other direction there was a thoroughly terrified rabbit that was obviously very glad that the dog went the other way. Now, that's not why I'm writing about this event. No, it's because when the dog came _back_, she _still_ failed to notice the rabbit, and ran straight back to the front door. Dogs are dumb.

    This brings a whole new way of looking at Schrödinger's cat paradox. If we replicate the cat's brain and way of thinking, is it a cat or not? What dictates life and what dictates death?

    @Nathan Obbards: I think it probably just means you couldn't use cybercat in the experiment; either that or instead of using acid or gunpowder, the system would have to cut power to cybercat or otherwise disable it to generate multiple states.

    @Nathan Obbards: I don't think you understands Schrödinger's cat paradox. It has to do with quantum mechanics. If I recall correctly, it has to do with some physicists believing that energy/matter exists in two states simultaneously, as a wave and a particle, until it is observed at which point it becomes one or the other. The paradox for Schrödinger is that if you apply this system to a cat in a box with 50% chance of being alive and 50% chance of being dead then the cat is both alive and dead until you look in the box at which point it is one or the other. The cat is just a means, it could as easily be a light bulb or anything with multiple states like water.

    @Nathan Obbards: I think it would simplify the paradox if the cat-in-a-box were Virtual in nature... If you wanted to ensure the state of the cat-in-a-box you'd simply unplug the cord and wait a couple seconds. It would be dead every time.

    @Nathan Obbards: Edit: You bring up a very good question, but I still think the virtual cat would not be the same one that lost power.

    Chances are a cat would come back alive if the system could handle a hard powerdown like that, but it would not be the same virtual cat that was there before because this new cat would have, at the very least, experienced a unique bootup that it had not experienced before, so arguably it is a different virtual cat that exists. Beyond that, chances are the cat lost everything it had in ram at the time of the power loss unless it was using that new-fangled ram that retains its last state. Of course if the developers include that technology they may have foiled my theory here.
