I would underline that. It's a bit of a problem that since 2005, anyone who could spell 'construction' could somehow make money with construction. That is not a good long-term state for an industry. And then, at the end of the 2000s, sustainable development came in, the EBM? came a bit, and then it was a bit dead in the sense of certificates you had to have. Then, thanks to the movement around Fridays for Future and the general global awareness regarding climate, there was really a switch where at the decision-maker level, I can really see it in the DAX companies, in the large medium-sized companies – actually DAX is even better than the medium-sized ones, I have to say, but that can't be referenced for everyone. It went from a nice-to-have, permission-to-play to a must-have. Before, it was cool and nice if you were sustainable, then for a while around 2015 it was almost irrelevant, it was all about capacity, and then from 2018/19 it's like: you can do it now or not. That's why people have to change in that direction, and this pressure is extremely positive. At the same time, there are many more technological possibilities today. For example, VR existed 20 years ago, but it didn't matter; the technology wasn't ready. Today, you can do a lot with VR and augmented reality, completely normal in reality. That means it's now applicable: 3D reality capture, computational design, robotics on the construction site – all use cases that are now for the first time really moving from the necessary egghead academia into the real, hard construction site life, still cautiously, but certainly rapidly in the next five years. And one topic that is always important for us: you just have to shed the narrow-mindedness of the construction industry and say, other industries have done it, for example the automotive industry. A huge creativity momentum and productivity momentum was generated through the collaboration between OEMs and suppliers. We have made initial thoughts with Alex Kraus at Knauf on how we defined this wooden exterior wall element with Opitz. We have partnerships with Hugo and many others where we say, okay, this is our application situation, and we ask our suppliers: let's think together how we can further develop this in our interest. And these are topics – we were completely sequential: someone planned something next to someone else, then it was awarded in bits and pieces. That is simply a system error in the construction and planning process, and it will change because it has to change.
