As the 21st century began, human evolution was at a turning point. Natural selection, the process by which the strongest, the smartest, the fastest, reproduced in greater numbers than the rest, a process which had once favored the noblest traits of man, now began to favor different traits. Most science fiction of the day predicted a future that was more civilized and more intelligent. But as time went on, things seemed to be heading in the opposite direction. A dumbing down. How did this happen? Evolution does not necessarily reward intelligence. With no natural predators to thin the herd, it began to simply reward those who reproduced the most, and left the intelligent to become an endangered species.

Unity stats counts active working devices out there. They cannot count phones in trash bin or desk drawer.
If you are a developer, market share shouldn't concern you too much, as it changes every month when something new comes to market. Installed base is what most people would go by.
There are very few reliable means of collecting installed base stats, but a cross-platform SDK from an ISV who isnt affiliated with any of the platform providers, powering many popular games would probably be a good first stop

Just like the world hunger was a solved problem the day we invented Philly cheesesteak sandwiches and rice crops. The march of technology is such a relentless marvel.
It is a nice solution in theory. The implementation details however would be very hairy and difficult. You have to agree to the protocol on what the anchor time for zero crossing is, you have to get power plants and large scale grid compensation systems to dance to that beat first. This in itself would be no small feat. And then somehow get all the small inverters GPS enabled, which places extra constraints on their installation locations etc.
And then, your entire power grid will have a single point of failure - GPS outage, or you will have to factor in redundancy protocols.
You do not understand error propagation.
Synchronizing at the point of connection does not mean that you are synchronizing with any particular "power plant", you are synchronizing with a relatively randomly distorted signal that gets its contributions in worst case from multiple neighborhood inverters that are also trying to sync and are all somewhat off, and nearby real world loads with different apparent power and other sources of noise.
Coordinating the power grid needs information, today the information carried for proper coordination ( AC waveform detecion by grid inverter ) is not sufficient to make things work at large scale.
Whether you transmit the coordination signals ( i.e. extra bits of information ) in-band ( over powerline, superimposed on the AC wave ) or out of band on a separate carrier is the question of implementation. Both in-band and out of band would have their upsides and downsides.
Fact of the matter is that todays grid is not built for that.
Simple case, assume there is a dozen or so high power solar installations in my neighborhood, delivering most of the peak power output. The requirement for grid-tie inverters is matching the phase within 1% of the 50/60hz waveform read at the connection point. The question is, _whose_ waveform is mine really following ? Is it the neighbors ? Which one is his following ? How does the error propagate and does it multiply ? That is the gist of the coordination problem.
I agree with most of your post, but i disagree with the assertion that grid "MUST be centralized". It must be well-coordinated, and centralization is one of the ways to achieve coordination, but not the only one.
Power grid currently is built with assumption of central coordination, that's why there are these growing pains with distributed generation.
Its not just frequency and voltage, there is phase and power factor, harmonics etc. Grid tie inverters are not simple pieces of equipment by any means - they try to synchronize and follow the grid power delivery by following grid input AC waveform at the point of connection, which is a limited bit of information and may not be fully in sync with macro-scale grid need at any given moment.
For a perfectly synched network you would have to have atomic clocks and low latency radio link network with each point of generation, that's obviously not going to happen, so hacks, power factor correction systems, extra reactive loads etc are and will have to be implemented.
Yeah, but if your energy density is so low that a supercapacitor beats it, you have nothing useful, as they will always have superior power density.
