 Tesla launched about two years ago or so. Last week they announced now they have charging stations for electrical power going all across America. You can drive from New York to Los Angeles for free. So with the Tesla, you pull up, you have a subscription to those stations. You pull up, you put in the power plug, and then it takes 20 minutes and your car is loaded. It's a supercharge called supercharge. Because clearly with this car, you can't use gas. So if you run out of power, you're in trouble. So the answer that what Tesla is showing us really is quite a simple principle is that the ultimate success of a change in transformation hinges on the ecosystem, whether the ecosystem is complete. I mean, imagine if you were driving a Tesla and you run out of power, you have nowhere to go. You have to call a tow truck because the ecosystem isn't working. This is why people don't have it in Europe. So it is an ecosystem. So really what it comes down to is that if you're trying to change how things work, and this is really what you're trying to do here obviously, is you have to construct the ecosystem around what you're trying to do. You have to complete the ecosystem. So in other words, your job is not to build apps, but to build the OS, the operating system.
