I'm surprised at something huge being left off the list - admittedly a political hot button, but still very important.
As a result of China's population control efforts, they now have a generation with a large dearth of women. What will the impact of this be? Right now the imbalance is around 20 million and rising. Combine that with a population that is expected to rapidly age and shrink over the coming decades...
The Chinese era of economic dominance may be rather short.
Economic interdependence isn't a bad thing, provided it truly is two way. We hear plenty of talk of our over-dependance on China and the economic vulnerabilities that come with that. I don't hear so much about, as you wrote: " it can no more do without China than the country itself could disengage from world markets and revert to a closed socialist economy."
The more interdependent we all are, the smaller and safer the world is. There is a lot of fear of China (both economically and militarily) in the US. How much is truly justified, I don't know, but the fact is it's there.
If we need them and they need us, and we all understand that we both need each other, the level of fear can drop and we cal all spend more time focused on building cool stuff.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
