Kurzweil famously predicted that by the 2030s, we will connect our neocortex to the cloud. In this book, he doubles down. He argues that connecting the brain to the cloud will not alter who we are, but rather expand our capacity. He uses the analogy of a smartphone: just as a phone expands our knowledge of the world, a brain-cloud connection will expand our intelligence directly.
