Some people always expect all kinds of crazy things, that doesn't mean they should happen as they expect. For example last year a lot of them were expecting the price to fall down to $1000 and obviously that was crazy and didn't happen.
This is the same, the bitcoin adoption is not something you can expect to happen overnight. It is a slow process that could take another decade or two. Besides these are just "investors" not adopters so you shouldn't even care about it in first place.
