Hmm. My comment is the most highly upvoted response to your survey at the moment, and the second highest upvoted one is by XiXiDu expressing basically the same position as mine, but I don't see it on your list. Here's a summary: we don't yet have enough insight to choose any specific answer or even to know if we're asking the right questions. We're facing an unsolved scientific problem. The wisdom of crowds doesn't apply here. If no one has yet discovered Maxwell's equations or Watson and Crick's double helix, no amount of surveying can lead you to the right answer. You have to do, like, actual math and physics and biology and stuff.
