 And now to Germany, futurist Gerd Leonard arguing there will be an abundance of energy in the not so distant future and the prices for energy will decrease sharply. Basically energy is pretty expensive and a lot of energy is a lot more expensive so if you're running a super computer that needs the power of 300,000 households you know it's just not feasible. I think in the near future we're going to solve a couple major problems. Battery is a huge problem so we're just about to get to the cliff of the peak of that right. So in five years we have that solved. You fill up your electric car once a month and then once a year and then once when you buy it. That's five or ten years away. So at that point basically energy harvesting whether it's water, wind or natural resources becomes very cheap because we have robots, we have AI, we have cloud computing. So the costs drop dramatically and then in 20-25 years the price will go towards I wouldn't say zero but you know energy like water which feels like it's free but it's not really free. Mr Leonard going on to say the future is coming much faster than we think. Machines are exponential humans are not and we're never going to be exponential and I certainly don't want to be exponential. I think what we need to do is we have to say well technology is going to be exponential. We use that in a safe and controlled and in a friendly way that we can still understand and then we build the human values on top. So we need to agree on what that is for example what I call digital ethics. We have to agree who's going to be in charge of data, who's in charge of my identity, who do I go to, what are the civil rights on the internet you know all these things need to be agreed on. So basically I think that exponential technology is a good thing but we should not strive to be exponential because we are not going to be right. We need eight hours of sleep, we can have 150 friends not 50,000. We are biological limited and we should accept that I think as a given for the time.
