Just spitballing here, but I thought I'd toss in that the long-term behavior of multiple orbiting bodies is chaotic. Even if you knew down to the miligram what all the bodies concerned weigh and exactly how fast they were all moving and in what directions, it's been shown that it is impossible to predict their long-term behavior even in an idealized environment, let alone with solar winds and asteroids and what not. So with all the computer's in the world, ending your days inserted into the wrong end of a dinosaur would be one of the less disastrous outcomes.
