Maybe "they" have long grown out of technology; surpassed the need for it, fulfillment was archived on other things, like the Self. So, contact is out of the question. We still walk alone.
My other take on the issue is that we are measuring these things by our own time span, what if the such lifeforms were born, grown and died in days, yet still found a way to conciousness and their evolutionary zenith? Maybe they have come and gone, there are no gaps, because there is no parallel to us.
