I'm completely agree with you David. I think originality is highly overrated and it's highly overrated in our culture but particularly in our industry. Whereas by contrast virtually every other aspect human life originality is less important than copying. Copying is our number one skill. So Isaac Newton, probably the singly most arrogant physicist there's ever been famously wrote to his friend. If I have seen further it's because I stand on the shoulders of giants. In other words I work on the basis of the work that my mates have done and everyone before them and so on. And Picasso famously said that talent copies is genius steals and which farris in New York style then to call his block. And then T.S. Eliot, the famous English Anglo-American poet, said that all poets copy just that the bad ones deface what they copy and the great ones make something better or at least different. This is so important that I can I can I play my game with the audience? If you'd like to play a game you can play a game because I think participation is on. So I'd like you we're going to all of you sitting in the front row you have made a mistake today. You can enjoy me please up here. Come up here. This is so 21st century isn't it? The audience is on the stage. Maybe it's late 1960s. What I want you to do is I want you to all stand there in one line and face me. And what will happen is that you will be tapped on the shoulder by the person behind you and then you'll turn around and watch what they do. And then you turn around tap the person in front of you on the shoulder. They will turn around and you show them what you see. Okay? You'll be tapped on the shoulder, turn around, watch, just turn around, do. Okay? And the audience watch very carefully what happens here. Go. Yeah, turn around. Don't look around. Turn around. Turn around. Turn around. Okay, turn around. Turn the shoulder. Very good. Very good. Turn around. Very good. Tap. Very good. And would you like to show the audience what you've just seen? And you at the front there. Can you have a look out? All take us line back to see what he's doing. There's a book like this going. It's great. So what did we see there? We saw a few bursts of people copying each other and then getting bored and doing something else. But when they did copy, there was a change quite quickly. If you'd like to just step forward sir, could you sir in the black? Show me what you did. Right? There's that's very different from what you've got to copy. Point being is that copying creates new stuff. Either by accident or some of you decided to do it on your own. I've got bored of doing this so I'll do something else. That's how it works. Copying is much more important than originality. Rad of applause. Thank you.
