Matrix Technology
Right outa "The Matrix" here's Infineon with a chip capable of connecting to 16,000 neuron connections.
Money quote...Vassanelli says. "It would definitely improve our ability to experiment and understand the workings of neurons, and this development could also provide a whole new way to store computer memory, using live neurons"
(Better than using us as batteries)
Clearly we're well on an accelerating path to enhance and repair human cells via electronics.
Just what kind of 'human' actually finally gets to explore deep space is 'in development'.
