An app is opened, but by the Apple Pay hardware rather than by the user. This keeps the interface simple and does not require any daemon in the OS; the user just pulls out her phone, touches it to the cash register, and authenticates with a designated fingerprint until a 'Done' checkmark pops up. Other schemes require the user to turn on the phone, go into a specified app, and enter a PIN.

The ACH transfer scheme being pushed by Walmart also requires that the user scan a QR code that is generated by the cash register as a challenge/response sequence. By this time, the other people in line at the register are starting to cough and shuffle their feet while the user wonders why he didn't just pull out his credit card to begin with. Small wonder that Walmart's scheme (which, because it also requires a central database of user information, has already been hacked) is so unpopular even in beta that chains using the system have been ordered to turn off NFC entirely to stop wholesale defection. This locks out all NFC vendors, including Google and all those European and Asian visitors who had been happy to hear that American retailers were finally about to exit the twentieth century.

Space Shuttle attempted to do what you describe, coming as close to that ideal as reentry dynamics would allow. It still required a 40-degree angle of attack during the hot part of deceleration. The final approach may look airliner-like, but the sink rate was something like seven times that of a Boeing, a requirement of the delta-wing design, which in turn was imposed by the need to reenter without stripping off the wings.

The Orion capsule may look like a throwback to the Sixties, but it's the most tolerant, safest design of all.

Both schemes are just part of the NFC standard, which has worldwide support. The problem with Google Wallet in favor of Apple Pay is that GW requires sharing customer data with Google. Better hope there isn't a breach. GW also requires the user open an app on his device and enter a PIN. AP just comes up when you touch an iPhone to the point-of-sale terminal, and authenticates with your thumbprint.

No it doesn't. It leads to the question.

But if we assume that all robots - all AI in general - starts by being created by a biologic intelligence, that doesn't matter. We have already established that robots work really well in space, especially for long-distance excursions.

The first intelligent aliens we encounter will be robots. Furthermore, the encounter will be by our own robots.

"Germany is leading all other countries by re-building its grid and moving to renewable energy on a very large scale."

Germany is also digging the world's largest strip mine, and for lignite, an energy source not fit for cavemen. And its push for renewable sources has run into a wall of eco-maniac opposition to the new transmission lines required to wheel power from sunny and windy places to urban users (like our envisioned "Smart Grid")
