You're right that there won't be another Facebook. Just as there hasn't been another Microsoft or Google. But thinking that there isn't going to be anymore large up and coming companies that change the competitive landscape is false. It'd be like saying in the 1800's that now that railways have drastically changed everything there won't be any new railways game changers. There wasn't much development/change in railways, but it was something new called airplanes that changed everything.

That's not a given by any means. For all we know, the next big thing is being started by some kid in a dorm room right this minute. I would hate to think it was otherwise and I believe there will always be a new disruptor. Technology marches on and we have not reached the end, not by a long shot.
