That is very likely. However, rather than buzzing around spending all that energy, if I were the alien version of NASA director, I would send only mental transmissions.
There is a good chance that we will see a lot of human form people when time is right. My psychic friend says that we will actually start trading with a planet whose beings evolved from fish in about 100 years. It will take that long to establish communication and transportation systems.
BTW, Since we are in the pseudoscience department, I had a dream last nght about sometype of EMP disruption in USA that caused a lot of problems. The electric power was intermitant, We lost a lot of satellites etc. The time factor could be 10 to 15 years out. It was not a lucid dream (that is, I did not wake up just after) so the info is sketchy. I think it will happen when one of our labs detonate a test EMP bomb but did not realize the magnitude.
