Imagine if the Internet Were to be Redesigned from the Ground up Today, How Different Could it be?

Keep in mind, this is a very hypothetical situation

Assumptions:

• We are not tied down by the need for backwards compatibility for the existing Internet
• The infrastructure would also be recreated from scratch
• The world will not face a crisis or collapse because of this
• The Internet is designed to best serve the needs and interests of people in the modern day. In other words, assume there aren't a handful of companies or governments that would influence the decision in a direction against the common benefit

Would the Internet look very different? This is surely an impossible question to answer correctly, but consider it an exercise in trying to imagine the ways the Internet could be made better if we did use the constraints mentioned in the assumptions above.

At the very least, we know there won't be IPv4 anymore!
