John Horgan in Scientific American:
Horgan: Neuroscientist Christof Koch has suggested that we get brain implants to keep up with machines. Does that strike you as a good idea?
Schneider: It depends upon the larger social and political setting. Several large research projects are currently trying to put AI inside the brain and peripheral nervous system. They aim to hook you to the cloud without the intermediary of a keyboard. For corporations doing this, such as Neuralink, Facebook and Kernel, your brain and body is an arena for future profit. Without proper legislative guardrails, your thoughts and biometric data could be sold to the highest bidder, and authoritarian dictatorships will have the ultimate mind control device. So, privacy safeguards are essential.
I have other worries as well.
