re: No point other than a new NEO that is a potential threat to Earth
If we can't deal with the threat by then we never will IMO. Apophis is close enough in time and the interval between 29 and potential impact is too short that if we wait until we know it's a threat we won't have time to address it. Not that you would disagree, I'm just elaborating on why a lower impct risk worries me more.
