In the 1966 film Fantastic Voyage, a spacecraft and its crew are shrunk to microscopic size and injected into the body of an injured astronaut to remove a life-threatening blood clot from his brain. The Academy Award-winning movie – later developed into a novel by Isaac Asimov – seemed like pure fantasy at the time. However, it anticipated what could be the next revolution in medicine: the idea that ever-smaller and more sophisticated sensors are about to enter our bodies, connecting human beings to the internet.
This “internet of beings” could be the third and ultimate phase of the internet’s evolution. After linking computers in the first phase and everyday objects in the second, global information systems would now connect directly to our organs. According to natural scientists, who recently met in Dubai for a conference titled Prototypes for Humanity, this scenario is becoming technically feasible. The impact on individuals, industries and societies will be enormous.
The idea of digitising human bodies inspires both dreams and nightmares. Some Silicon Valley billionaires fantasise about living forever, while security experts worry that the risks of hacking bodies dwarf current cybersecurity concerns. As I discuss in my forthcoming book, Internet of Beings, this technology will have at least three radical consequences.
