 Dear Lord Forster, Dear Kent Larsen, Dear Gesar Ziemer, Dear researchers from the MIT Media Lab and the International City Science Network, distinguished guests from Hamburg and all over the world, welcome to Hamburg. My today's 90-minute lecture is about the basic principles of AI in smart cities. Oh wait, sorry. Today it is without. So Alfie without a lecture, good luck for you. So no, seriously. Firstly, I'd like to welcome you, friends from all over the world, to the third city science summit, taking place for the first time in Hamburg and I think the city of Hamburg can be proud that you have organized such a well-working conference and I hope that you're gonna enjoy the next couple of days here in Hamburg. Secondly, I have to congratulate you and thank the whole CSL team and especially Gesar, not only managing director of the CSL, but also vice president of the HCU, our university. And I think it is a special applause only for you because you have done so well. It is outstanding your efforts and I think for the city of Hamburg as well as for the HCU, it's a great effort that you bring it straight forward to make a better city out of Hamburg. So congratulations. Thirdly, I'd like to address the main motto of the conference. It is cities without, I really love that and Kent told you what it means, cities without. So there are many withouts, without cars, without pollution, without housing shortage. That would be great as cities, right? We all love that, we wanna have that and we wanna have that right here, right now. But I think there's another without and this is the most important thing for me and this is the reason why I wanna talk about that shortly. For me, it is cities without fear. If we have worldwide people suppressed, they have to flee, they have to be refugees because of oppression, wars and dictators, I think our cities have to be the place for those who have lost everything. So and when I heard the first time about HCU and they asked me if I'm interested in the position of being president there, you start Googling, everybody does it, right? So and I found finding places and I was deeply impressed about finding places and I read a lot about CSL and that was really so good that I said, yes, this is a fantastic university, I have to do that and luckily I won. So in a free world, I think we have to ensure and I think this is very important, we have to ensure that no right wing parties or presidents building walls stop us from being free and stop us helping people who are in need. For me, these are the cities without fear. For the next two days, I'd like to wish all of you a great conference, fantastic exchange with older new friends, new experiences, insights into the absolutely hot topics and the research on cities and all around this area, fun also and friendship. I hope that this is the conference you do love and you do remember for a long time. Thanks again, Gesar Kent, now it's up to you, enjoy the show, thank you.
