Yes, big data and supercomputers doesn't equal omniscient. If we can model things inside Jupiter's orbit well 50-100 years out and do enough R&D to elevate the logically proposed solutions from theory to engineering we should be able deflect most of natures challenges and correct most of our own 'oops.' Our history in space shows the last step is necessary, beautiful theories aren't enough. Things incoming from beyond Jupiter become harder to spot, predict and this avoid. Someone needs to deduce where to position sensors to collect useful data on potential impactors that can't be acquired near Earth and send suitable probes there. Prioritize shrinking our bind spots. First nearer and riskier. Eventually further out.
I have long felt that the way to do this was to allow commercial ventures in space.
For instance, the right to name new objects belongs to the discoverer. If we changed that to allow the financer of the sensors and telescopes that made the discovery to designate names, we might have to live with comets named Budweiser 2020, but a lot of money would come into the search for new objects in space.
