Did I mention how big space was, just how giant the distance between stars and galaxies?

The average span of existence of a mammal species on earth is around a million years, we're near that, and we've been communicating in a way visible to others for what, .01% of that time? enough time to reach the tiniest, absolutely unmentionably small percentage of the known universe with the weakest signals.

What would be a paradox, or at least an event of unimaginable unlikeliness based on what we know now, is if anyone showed up and got back to us.

I don't see any paradox in the vastness of space (and the only recently confirmed existence and proliferation of exoplanets), the likely reproducability of evolution (and the seeding of planets with organic matter from comets) and the fact that we have never met aliens.
Did I mention that time is very long? This planet is what, 6 billion years old and we've been around for on six thousandth of that and emitting radio for one 10 thousandth of that...


...reminded me of...

Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space.

(a) assumes we are sentient - debateable
(b) you think we need a sense of perspective on a rugby forum? - may I redirect you to GWLAD or The42 - or any Welsh regional forum

:D

Because that's where I learnt the meaning of liff.

Life developed very quickly here, it should have done so closer to the centre of the universe, ergo other civilisations should have come and gone and we should be picking up signs of their existence even if they are extinct. This planet emits radio waves across a huge frequency range. We have launched satellites that have gone interstellar. Surely they have too and should have done so from multiple solar systems millions of yrs ago.


Well borderline interstellar, and only one so far I thought though another might be soonish (I read reports of changes in the radiation environment over the summer). But that won't help as it's attempting to beam directed signals at us and won't be leaking anything willy nilly. As an aside I love Carl Sagan's response to the question "why didn't you have Bach on the record rather than Beethoven so that aliens could truly appreciate what we can do" - because that would be boasting.

I don't know if it's true, but I'm believing it anyway as it's so good.

Anyway, to your perspective on it. If I accept what you say as being true (and I don't necessarily) we would also have to be looking for the tiniest neutrino needle in the largest haystack on something like an NSA scale of investment ramped up to deal with the vastness of space.

And we just aren't. We'd need to redesignate those hypothetical aliens as "terrorists" or "illegals" before that would happen.

Ep4 AI has scared the sh!t out of me and I will now commit myself to hunting down those who work to develop it.
The episode described as an example how a self improving AI designed purely for the manufacturing of paperclips could result in the end of mankind and many other risks, explanations etc.
