> To do this, as claimed by Musk with 1,000 microelectrodes within an hour with "surgery without anesthesia", in the pulsing brain with no neurosurgeon present is not just impossible... The not-so-secret secret sauce that will make it possible is AI. I'm certain it will be possible, in the not too distant future, to build AI models that can successfully control microelectrodes to penetrate into the cortex and find cells with superhuman precision. Consider that we now have "dumb" AI machines like GPT-3 that can model the statistical structure of human language. And note that there's nothing new or interesting about GPT-3's design except its size. GPT-3 is just a sequence of really large transformer layers. I can imagine a robot with the scale of a GPT-4 or GPT-5 successfully controlling those microelectrodes.
