Mixed reality devices.

The lowered cost of solar, wireless, and battery powered homes allows for the creation of inexpensive smart homes that allow for better quality of life and access to digital world at an affordable cost.

Low cost IoT devices are a precursor to an explosive growth in Smart City deployments that actually make a difference. Traffic cameras, air quality monitors, all the way to electric meters and household devices. However, the administration, controls, and understanding of the massive information that comes from IoT poses a major challenges for developed countries and developing countries alike.
Solutions from startups like Nubix and Tanium, which provide inference, machine learning, and adaptation at the Edge are what will cause "The Tipping Point". Obviously major corporations such as Google and Apple are focusing on this space. For example, when any Google Car has an issue, EVERY Google car learns from that event. Classic machine learning at the Edge.
The traditional model of centralizing all data and crunching it to find value doesn't work when the data volumes increase by 1000x over today's large systems. So, forget centralized databases and BI/Analytics tools, per se.

1.Block Chain sort of approach will be used for validating transactions as well as data integrity.
2.Each living human being, will have a set of unique data stored or embedded in unique "planet id" for easy verification.
3.Each home will produce electricity and purified water using hybrid solar/wind generators. Grid electricity will be used for back up or for emergency.
4.Each home will have smart effluent treatment facilities
