Samsung Electronics president Young Sohn today sketched an almost dystopian future in which every detail of your life — all the way down to your individual DNA — is tracked by vast "bio data banks" that store your genome, help diagnose diseases, offer prognoses, and assist with disease prevention.

The databases will be part of an explosion of data-based businesses that will know almost everything about you, in a world of "sensor pervasiveness." Data sensors will provide fantastically granular detail in tracking your blood, your car, your food, the temperature of your home, and use artificial intelligence to inform maps and public transportation, he said.

To give you an idea of just how far we are already into this future, Sohn told the Web Summit conference in Lisbon that there are already 340 trillion-trillion-trillion IP addresses on the planet (that's 10 to the power of 37), mostly inside connected devices that already have the ability to talk to each other. For scale, there are only 100 billion stars in the galaxy, and only 100 billion neurones in the average human brain.

In an interview with Business Insider after his speech, we put it to Sohn that there was a lot about his vision that was troubling.

"I worry about that," he told us. "That's why I brought up these questions of ethics. I mean, I think we should really worry about ethics. What is right? What is wrong? That's why I made a comment, we've got to be principle-driven. And the research? Great. But research for purpose, not for using that data to take advantage of all human beings out there."
