There's always the problem of when.

While it's becoming more likely that a life supporting planet exists outside our solar system, we have the problem that mankind's recorded history is measured in thousands of years (and more than likely will only be measured in thousands of years) while the universe is a tale of billions of years.

I'd still say we are likely to see artificial satellites at some point, as our own would likely survive for millions of years in some capacity (even as junk), but the possibility of direct communication is probably never going to happen.
