The coolest part about this is probably how little energy it needs. It's about 20 Watts. Current node sizes are already smaller than axon diameters. If it weren't for power, we could probably scale up manufacturing processes of current semiconductor technology to build giant room sized chips but we simply wouldn't be able to cool those things. Instead we are forced to wrap a ton of metal around them and plastic and air and provide extensive cooling.
