Significant developments in the future of the Internet, in the order that I believe they will occur/are occuring:
1. IPv6 implementation, growth of the Internet of Things (Internet connected appliances such as microwaves, refrigerators, toilets, etc).
2. Core redesign and implementation of the essential protocols used for email, web, public-facing file shares, etc, with secure mass use in mind this time, rather than the more responsible and educated military/university use that ARPAnet was originally intended for.
3. Mesh network. Instead of relying on an ISP, your Internet devices will connect wirelessly with each other and other devices that are relatively nearby, which will in turn do the same, and so on. Each will act as a private client device and as an public Internet traffic router.
4. The Internet of Things finally includes biological implants and begins to include an Internet of People.
5. Biotelepresence services begin being offered. (Car broke down? You'll allow me temporary access to your bionic eye feeds, and I'll tell you what to do to fix it for a fee.)
