The evolution of the Web today is happening faster than the transition from Web 1.0 to Web 2.0 due to processing power, bandwidth and storage, "creating a curve of exponential change.
Web 4.0 is about the ultra-intelligent electronic agent. This agent will "recognize you when you get in front of it because all of your devices are getting a little camera. And with facial recognition, they’ll know it’s you." Burrus says you will be able to give your agent a personality. It will say to you things like this:
"Good morning. You're flying to Boston today. Take a raincoat, it's raining. By the way, that fight you were taking, it’s already been canceled. Don't worry about it. There was a mechanical. I've already booked you on a new one. I'll tell you about on the way to the airport. But remember you’re going to exercise every day and I’m here to remind you that you’re going to exercise." And you might say, “I don't know if I want to exercise today,” and It'll show you a nude profile of yourself. And you’ll say, “You know what, I think I'm going to exercise today.”
