David Roberts is a tech optimist and regarded as one of the world top experts on disruptive innovation and exponentially advancing technology. He believes we will live many times longer, become better humans, will have endless energy and products and will not destroy ourself in the proces. He also works on EV drones that have the size of a suitcase and can fly a 120kg human at 100miles/hour. At SingulartyU I interviewed him. In 50 years we will write DNA more than we write e-mails. He thinks the cost of writing DNA will go to almost nothing. How do we cope with this change?
