breaking the last empire : americans need to vote now are they separate and superior speciesn OR are they like the rest of the 8 billion of us? new summer 2019 : drucker ::::60 years ago dad, norman macrae, started the first of 100 conversations on AI (Artificial Intelligence), He had just surveyed how Japan was rising (lifting potentially Asians everywhere out of colonial era poverty) round brilliant engineers (bullet trains, container superports , microelectronics, the most reliable engines in the world) - from tokyo he brought back a pocket calculator- what would schools and the world be like if everyone had one of these?

Within a few years the world was debating if tech helps man reach the moon is there any mission impossible on earth.
5G 2020s (4 3 2) 1 G 1970s
And Gordon Moore of Intel had just written a paper promising that microelectronic engineers would improve tech 100 fold every G decade to 2020s -that's a trillion fold more powerful microchips in 2030 than man raced to the moon with. So who's knowledge should teachers and everyone linkin to now if millennials are to be the first sustainability generations and THE UN 17 sdgs are to be celebrated as possible wherever the next girl is born. We welcome your nominations: here are a few examples back from the future of 2030 followed by an approximate chronological order.

Elon Musk receives FCC approval to launch over 7,500 satellites into space

SpaceX plans initially to launch 4,425 Starlink satellites into a low-Earth orbit followed by an additional 7,518 satellite at an even lower orbit. The first group of satellites will operate at an altitude of 1,110km to 1,325km and will form the backbone of the company’s Starlink broadband service. The additional satellites will circle the Earth at altitudes from 335km to 346km and will boost capacity and lower latency, especially in densely populated areas. Because of these low orbits, SpaceX says its planned Starlink broadband network will have latencies as low as 25ms and gigabit speeds that will rival existing cable or fiber optic systems. Not only will it be fast, but the Starlink network also will reach those areas that have poor or no internet connectivity.
FCC rules require SpaceX to launch 50 percent of its proposed satellites within six years and all of them within nine years unless a waiver is granted. To put this deployment in perspective, there are currently only 1,886 active satellites presently in orbit. These new SpaceX satellites will increase the number of active satellites six-fold in less than a decade. A recent simulation by Mark Handley, professor of Networked Systems in the Department of Computer Science at University College London, visually shows the off-the-charts scale and complexity of the network.
SpaceX already is making progress on this formidable plan. On February 22, 2018, the company successfully launched its first two Starlink test satellites, Tintin A and Tintin B, from California’s Vandenberg Air Force Base. These satellites are being used to test the Starlink network on a small scale and demonstrate its feasibility. It is not known whether these test satellites will be used in the network when it finally is brought online. As part of its approval, the FCC requires SpaceX to have a debris mitigation plan to keep the space junk problem from getting worse.
