Scary theory about aliens (pt 2)

Probably a gross oversimplification, but my hypothesis is very basic: odds are high that the gap in technological capabilities between humans and other (alien) civilizations is huge, in both directions. Those aliens who have managed to evolve technologically beyond the point of Singularity have certainly integrated with A.I. (Allowing a quantum leap in technology) These E.T.'s have been visiting us (many examples of unexplained encounters) but since they possess technologies too advanced to be explained by our relatively primitive minds, we have not yet recognized/accepted the new reality. The good news is obvious.... if E.T. had any intent to do harm, we would be gone by now. Any species with such advanced capabilities could have exterminated us a long time ago, yet their encounters with us remain benign and controlled. If we don't allow our fears to cause aggressive actions towards them, we'll likely get a message from E.T. at some point but only after they have decided humans can tolerate a new reality without going bonkers.
