Will never happen. Can't see it staying higher that say 300/400 for any length of time. if it did it would price the normal person out of bitcoin as a currency. It would be bad for 95% of users if it were to go that high..
Even it is impossible to be happen, its only a question that the person who made it. He's just getting other's opinion what there gonna be their response to this. Perhaps the good opinion will be a good learning tools to some other members here.
