Not so long ago, I was thinking in that way, too. But I've come to see my recent way of thinking as being quite 'uniformitarian'. I've had a good hard look at my assumptions, and seen that there are a lot more factors at play that I was not considering.
Think about what would happen, for instance, if there is a pole flip.
Just a magnetic one => no problem
But, as did understand it, which might not be correct, after a magnetic pole-shift there is probably a "physical" pole shift coming. With a physical pole shift our survival chance here seems to be 0.3%.
