Brain-computer interfaces (or BCIs) are the ultimate tale of convergence. They sit at the intersection of nearly everything in this book, including biotechnology, nanotechnology, and materials science—which, as we’ve seen, are rapidly becoming all the same industry. There’s also quantum computing, which gives us the ability to model complex environments like the human brain, and artificial intelligence, which allows us to interpret what we’ve modeled. And high-bandwidth networks that allow us to upload neurological signals into the cloud.
