Not going to happen. It's a mindshare thing. If there are 10 million people who think I may as well have a bit of my portfolio in bitcoin that gives it value and that's probably not going away in a hurry.
If anything it'll get worse as it goes from 1 million to 10 million to 100 million. Back when 1 bitcoin = 1 pizza there were perhaps 1000 people into it?
