If the minimal level of meaningful communication is via such tools as radio telescopes then we could be in for a longish wait. OTOH if we lower our standards somewhat then we already have meaningful communication with some other species. Naturally, the other species aren't too interested in communicating their thoughts (if they have any) about what they would label (if they could) arcane issues (which, incidently, most humans don't give a FF for).
The question of whether there are extraterrestrial intelligences like ours (ie using sophisticated tools) might depend on how evolution as a process works. We can argue that since humans exist there has to be an unbroken line of ancestors to at least the first living forms. Looking forward from the POV of the first of these forms we could ask whether the possibility of human-type intelligence already existed or whether this possibility itself changes according to circumstances.
