"Do no evil" rule still applies.
And what exactly happens if someone breaks the rule?
Will someone stronger punish them? And what exactly happens if someone stronger breaks the rule? Is the majority together stronger than them, and the majority will punish them? And what happens if majority breaks the rule by deciding that some minority does not deserve any rights? It could be any kind of minority, even one that does not exist today. What if someone reproduces wildly? Exponential growth -- and after a few generations even 1000 miles with nanobots won't be enough for them; and by the way, at that time they will be the majority. Also if someone uses nanobots to strategically prepare for the war, they can be stronger than the majority that has other preferences; and also will have first-strike advantage. I don't say this situation is impossible, just that a mysterious answer is not enough. Maybe some solution will develop naturally; but maybe we really wouldn't like the solution.
The trends are clear, more and more work that was previously done by humans are being shifted to automated systems. Factories with thousands of workers has been replaced by highly efficient facilities containing industrial robots and a few human operators, bank tellers by online banking, most parts of any logistics chain by different types of automatic sorting, moving, and sending mechanisms. Offices are run by less and less people as we're handling and processing fewer and fewer physical documents. In any area less people than before are needed to do the same work as before. The world is becoming automated.
These developments are not only here to stay - they are accelerating. Most of what is done by humans today could easily be done by computers in a near future. I would personally guess that most professions existing today could be replaced by affordable automated equivalents within 30 years. My question is: What jobs will be the last ones to go, and why?
Often education is pointed out as safe bet to ensure being needed in the future, and while that is true its not the whole story. First of all, in basically all parts of the world the fraction of the population with an academic degree is growing fast. Higher education will probably not be as good as a differentiator in the future. Second, while degrees in the fields hot in the future is hot in the future there is no guarantee that the degrees hot today will be of any use later on. Third, there is a misconception that highly theoretical tasks done by skilled experts will be among the last to go. But due to their theoretical nature such tasks are fairly easy represent virtually.
Of course as we progress technologically new doors are opening and the hottest job year 2030 might not even exist today. Any suggestions?
