 And then we have the Internet of Things. Many of you may not know what this is, but the Internet of Things is essentially the concept that whatever we are doing as humans is now happening between machines. Here you see the connected traffic light. This light was $45,000. Four years ago it's $3,750 now. And this traffic light and street light connects you and figures out who you are when you're walking by. It provides Internet access. It measures the air quality. It sees how many people are walking by at what time, so it can regulate traffic. It does all of these things that makes it smart. I mean, apart from the fact that this is an extremely powerful technology, again, we could save 40% of energy cost if everything was connected. And Cisco says we're going to have 75 billion things connected. Now our wristwatches, our glasses, our suits, our traffic lights, our sensor networks, everything. Apart from that, it's also a scary thing. So what happens to our personal data? What happens to our privacy if the trash can knows that I've walked by? Big question.
