Is anyone else terrified by the idea of wireless electricity?

The news that scientists at MIT are successfully pioneering "witricity" scares me to death for some reason - I just don't like the idea of it. Using resonance techniques (and a two foot receiving coil) the system has been proven to power gadgets wirelessly over a distance of up to 7 feet, paving the way for a battery-free utopia where all our gadgets are kept topped up wireless networks at home and away - but something about the idea of this kind of energy resonating about the place feels me with suspicion...
