Arthur Clarke was hired by us (my predecessors) to write Childhood's End to slowly get people used to the idea that the individuals who very benevolently and very distantly run our planet are NOT evil beasts intent on enslaving us or some such nonsense. In fact, UFO sightings are often our protectors chasing off poachers and tourists. Remember the famous NASA vid where a warning shot was fired and the intruder speeds off in the other direction? That was actually the equivalent of teenage joyriders out for a lark, so to speak, which is why they were not terminated.
Our protectors are actually very kind and benevolent, giving us small bits of technology to improve our lives. As I understand it, a much more efficient method of utilizing solar power is in the works -- a storage unit the size of a large thermos will replace all the old batteries that we used to require for storage. This is a great gift they are giving us.
In short, the future is very bright and will finally 'arrive' once we achieve global governance (actually much closer than anyone not in the know thinks).
There. Bash away gents. I know you won't believe me but my telling you and you knowing doesn't alter anything. I just felt like telling the real deal for once.
