The brain is a complex compact analog chemical and quantum computer. We don’t fully understand how it works, let alone how to interface with digital technology. We’ve only begun to have success with blocking or stimulating certain regions that are dysfunctional. That’s not to say it’s impossible, but rather really difficult and requires many disciplines to accomplish.
But there are some ethical boundaries, protections, or questions that need to be considered. Such as, if you can upload information into the brain, what stops the technology from downloading information out of the brain? And, if a person can interface with a computer, are they human anymore? Where does the human end and the computer start?
