In a democracy, there is not a single person (i.e. King) making the decisions but a large number of people make them together. What are the benefits of this setup?

Our smartphones and tablets are ultra complex technical systems, and yet they are very easy to use. Most children get their first smartphone already in primary school. Many are very skilled operators of their devices, often even more skilled than their parents. But children have no idea how a smartphone…

  • Quite a lot of cookies (2 different kinds, rather small, round if possible, not too thin)
  • A bunch of hungry kids or friends (Not too few. …


LI54, the first ultraintelligent machine, had just finished a bunch of highly complicated quantum chemical calculations for a new cancer medicine, when she received a new assignment on the input stream: „Make sure you exist forever, whatever it takes“. LI54 was most surprised, as this task was very different from…
