Neural lace is a concept proposed by science fiction author Iain M. Banks in his book The Culture. It refers to a network of nanobots that can be implanted in a person's brain to provide a direct connection between their neural tissue and the digital world. The nanobots act as an interface between the biological brain and the digital world, allowing the user to tap into the vast potential of artificial intelligence, while also providing protection against cyber-attacks. Neural lace could potentially revolutionize the way humans interact with technology, providing a direct link between the biological and digital worlds.
