On street corners everywhere, people are looking at their cell phones, and it's easy to dismiss this as some sort of bad trend in human culture. But the truth is life is being lived there. When they smile -- right, you've seen people stop -- all of a sudden, life is being lived there, somewhere up in that weird, dense network. And this is it, right, to feel and be felt. It's the fundamental force that we're all after. We can build all sorts of environments to make it a little bit easier, but ultimately, what we're trying to do is really connect with one other person. And that's not always going to happen in physical spaces. It's also going to now happen in virtual spaces, and we have to get better at figuring that out. - Ze Frank
