Main Question or Discussion Point
In the recent past, I've leaned towards no. The reason being that space is a 4-dimensional haystack. Even if a region in that 4D space contains advanced extra terrestrials and we scan it, the extra terrestrials would not necessarily be using EM waves for communications. If extra terrestrials were using EM waves, we would not necessarily recognize a signal if we were looking at it. Wireless EM communication is very much in it's infancy here on Earth. It will likely look very different in 10,000 years, if it is not superseded by some other technology. I'm not even positive that human civilization will exist for another 10,000 years.
