Would you mind posting your reasoning, instead of just posting your conclusions and an insult?
I should clarify that I was intending to set some sort of boundary condition on the possible futures of life on earth, rather than predicting a specific end to it: If life comes to no other end, at the very least, eventually we'll get asteroided if we stay here. This by itself does not justify killing people in a fight for asteroid-prevention; so what would justify killing people?
Would you mind posting your reasoning
Timescale of life as we know it continuing to exist: Short
Timescale of killer asteroids hitting earth: Long
It's probably easier to build an uncaring AI than a friendly one. So, if we assume that someone, somewhere is trying to build an AI without solving friendliness, that person will probably finish before someone who's trying to build a friendly AI.

further edit:
Wow, this is getting a rather stronger reaction than I'd anticipated. Clarification: I'm not suggesting practical measures that should be implemented. Jeez. I'm deep in an armchair, thinking about a problem that (for the moment) looks very hypothetical.
For future reference, how should I have gone about asking this question without seeming like I want to mobilize the Turing Police?
