Someone said something in a way "if they are intelligent why they don't try to communicate with us?" As an answer to this I'd say. Pardon me, I have forgot his name, an scientist asked "why we don't try to talk with the ant colony?" The point here is that (if they are "aliens") they might be on a far more larger scale of development compared to us. Therefore, from their point of view, we might be that "ant colony" to them so why would they try to communicate with us at first place. Of course, this does not have to be true but it surely has sense.

Hearing this makes me sad. There are so many nice memories from my childhood and teen days related with Sound Blaster. It gave me so much of a great time...:(

Yeah, I definitely agree with you. Image looks really great. Yet, pardon my little knowledge about the subject in matter but I am afraid that even with this and other similar, latest discoveries, we are way away from finding the answers. While discoveries like this should gives us some answers they are actually only adding new questions to the list making our understanding smaller than it was. Of course, we are going into right direction but I am afraid complexity is becoming way bigger than we are finding the answers.
