Everything will be automated but there will be at least one pilot just for 'emergencies'.

That will happen in the beginning. But as people become comfortable with automation, it will be dropped. Would I fly in a pilotless plane today? Nope. But once they have flown 100,000 flights without any incidents, then sure. Most aircraft accidents involve pilot error, so once the bugs are worked out, the pilotless planes should be safer.

I saw Tomorrowland. It sucked. The plot made no sense, and most of the special effects were pointless (other than helping to keep the audience awake). The moralizing "everyone should feel guilty" ending was anti-climactic. I am happy to hear that it is bombing, and I regret seeing it.

Can be if you walk the mark to the nearest ATM.

That involves much more risk than a quick snatch-and-grab mugging. You will be with the mark for much longer, meaning more time to get noticed, and ATMs have cameras. You will likely need a weapon to intimidate the mark, meaning a longer prison sentence if caught. For what, maybe $300?

A simple cost-benefit analysis shows why this type of crime is rare.

Anything that really requires a mind rather than a simple result of calculation or mechanical action will likely not be replaced without some big advance.

Some things that used to take a human no longer do. For instance, image recognition has improved a lot in recent years. Banks use computers to read and process handwritten checks because they make fewer errors than humans do.

So then we have a long lasting energy source!

Yes, very long. But a solar mass black hole would have a temperature of 60 nano-Kelvins, and would emit 1e-30 watts. If you used all the emitted energy from the black hole to charge a AA battery, many of the protons in the battery might decay before it is fully charged (assuming protons have a half-life of ~1e33 years, which has not been experimentally verified).

So if a mug you, it is because I am being oppressed?

No, it is because mugging pays better than the available alternatives ... except it mostly doesn't, which is why muggings have drastically declined over the last few decades. Today, people carry credit or debit cards instead of cash, and used cellphones aren't worth much.

Bullshit. You really think someone who steals for a living will decide to flip burgers instead?

Yes. You should read Freakonomics. It is a superb book, and in one chapter he explains the economics of crime. Teenagers selling crack on street corners were making $3 an hour. Many of them asked the researcher if he could get them a "good job" as a janitor at the university. I think many criminals would be glad to flip burgers if such jobs were available in their neighborhoods.

They'll just find another crime that pays.

If the other crime paid, then another criminal would already be doing it. Expertise in one type of crime doesn't automatically help in other crimes. For instance, burglary skills are of little use to a Wall Street investment banker.

And as soon as one form of crime is understood and deterrents introduced, won't the (successful) criminals simply move their attentions to another neighbourhood, modus operandi or equally illegal field of endeavour?

No. Most crime is based on opportunity. More opportunities means more crime. Fewer opportunities means less crime.

This initiative doesn't seem to address the basic issue of the number of criminals

There is not a fixed number of criminals, nor a fixed amount of crime. If crime doesn't pay, potential criminals will do something else, and as crime in an area falls, businesses invest and other job opportunities tend to open up.

In general human intelligence tries to turn back natural entropy. And we are getting better at it.

Only within limits. Think of human ignorance as a doughnut. It is shrinking because the "hole" of things we are learning to do is expanding. But it is also shrinking from the outside as we learn more and more things that are impossible to do. The more human knowledge grows, the more confirmation there is that some things, such as faster than light travel, reversing entropy, etc. are fundamentally impossible.

Black holes dissipate over time.

Yes, but very slowly. A black hole of one solar mass would take about 2e67 years to evaporate through Hawking radiation. The time to evaporate goes up as the cube of the mass, and some black holes are 10 billion solar masses, so they would take more than 1e97 years to evaporate.

Any current black hole with a mass larger than earth's moon would actually be growing, since the cosmic microwave background being absorbed is more than the Hawking radiation being emitted. They will not start to shrink until the universe cools off and the CMB dissipates, far in the future.
