 So my work is about four sites, it's about observations. And before I get going, I would like to encourage you also to spend 3% to 5% of your time on four sites, which is to look at what's happening, observe, and work about five years into the future. If you do that, your job will be safe. And this is one of the key issues for companies is not looking at what could be, but looking at what is. And of course, you have to look at what it is because that's how you make a living. But 3% to 5% Google does about 10%. The engineers are allowed to do 20% allegedly. I don't really know how that actually works anymore. But this is a very, very important thing for our future.
