And even that comparison is probably rather generous.

I'd say we have better odds of inventing sentient AIs first.
if you see my previous posts, you'll see that I posted that "in the universe, there will probably be more than two civilizations with intellegent capabilities" or something like that. :P The example of just TWO specks of dust is, im not trying to make you angry, kind of stupid. If any of you watched any kind of Star Trek before, you will know that there are different species of aliens, such as Vulcans, Klingons, Humans, Romulans, Telerites and much much more.
So, if you add lets say 10 specks of dust, or 100 specks, the odds would increase. There might even be thousands or millions of specks of dust!
