No, we are very far from anything like that. I would watch Neuralink's recruiting events for a sense of where things are. They are trying to make a robot that will insert dozens of threads with several hundred tiny electrodes on these threads. This will allow reading a high-resolution picture of that part of the brain's activity. You can then hook this up to a computer and train yourself to map your brain's signals to some desired output (typing, moving a wheelchair, robot arm, etc). They talk about "writing", but that is just providing feedback, ie they send in signals and you train to interpret them as something. If they are successful, you can expect to have an accessible (ie, couple thousand dollars) brain-computer interface covering a tiny portion of your brain sometime in the 2030s. New knowledge would necessarily need new connections between between neurons, ie you have to grow and connect neurons in a very particular and intricate pattern. I think we're still at the "just barely trying to understand wtf is going on" stage. If you'd like a more in-depth intro to the state of the art, Jeff Lichtman's work on connectomics is a great place to start. Here's a 3-part lecture: https://www.youtube.com/watch?v=MtTOg0mzRJc You can skip ahead to part 3, where he describes the absolute state of the art machine they are building which will be able to map the structure of a tiny slice of brain <1mm^3 part of a brain using advanced optics, robotics and machine learning. It's quite humbling. |
