I've read one truly honest comment, by an expert: he stated some years ago that We are not in the IT age, we are heading towards it.
We're on the way, this is still experimental. The days of Battlestar Galactica or Stargate Atlantis are way ahead. Personally, I think the days when your phone was connected with wire to the wall, were safer. Can't remember who's law it is, but he made the remark that Given a present time in a present place, only a limited amount of wireless traffic will fit in atmosphere. You see, all electricity creates magnetism, and the Earth is magnetic. Thus, by feeding our surroundings, we interfere with Earth. We've had some storms in Finland, and I came to think, are these some sort of electrical storms?
No panic, though.
