Why we don’t hear ET

Few days ago I came across this article on Slashdot, it’s about how aliens can’t hear us, because we want to be more and more economical with energy and that’s why we have directed all signals from satellites directly to Earth, so we don’t waste energy with sending it to open space.

So that got me thinking… why SETI didn’t have any success (except WOW signal). Probably, aliens (if they exist) also became more economical during their development like us, and so they don’t send a lot of signals into outer space and that’s why SETI antennas get only static.

There could also be another reason why we don’t hear them, and that’s because they don’t use electromagnetic waves as means of communications, like we currently do. Maybe they’re transferring information using quantum teleportation that we discovered recently or maybe they discovered technology that we can’t yet imagine, because we’re form technological point of view in a stone age in comparison to them.
