I hope this will sway the governments of the world to allocate more resources towards aerospace technology, seeing as how "space exploration is our fucking destiny, you inbred redneck" is not good enough of a reason for politicians...
Not at all. It didn't hit us, it didn't cause any damage, therefore it's never going to be a problem.
If Tunguska had happened at a major population center, either the affected country would have gone to war over it, thinking someone else had attacked with an incredibly powerful weapon, or else we'd have an armada of spacecraft orbiting Earth, augmented by ground-based telescopes, looking for anything else that wants to come flying out this way.
(Then there are the Bible thumper types who think that God would never allow an extinction-level event to occur in the first place - or else that it would be a
good thing to have happen, because then we'd all go to Primate Heaven.)
