Seems like every other month we see a story about how a newer and smaller planet is discovered around a star. I think it'll only be a few more years before we find some kind of life on one of these planets ... do plants count?
Obviously Sharks with Frickin' Lasers is possible right now, but I don't see a whole lot of research going into this discovery.
I find it odd that Human Level AI is winning at the moment. I'm not all that familiar with the current state of this technology, but it seems at first glance to be about as hard as World Peace.
Anyway, my money is on Aliens long before AI or Sharks with Laser Beams.
