Here's the way I view it. If any industry or business can be potentially disrupted by a tech company in the next decade or two, they will. I think to bet otherwise is naive. Now, that doesn't necessarily mean that all currently entrenched interests are going to go away, obviously not, but most of them are going to end up in a fight for their lives at some point, and many of them will end up losing.
So many businesses today are profitable because they have a monopoly or oligopoly on some aspect of a supply chain. The onset of ubiquitous computing, network connectivity, automated manufacturing (3D printing et al), and so forth will disintermediate damned near everyone. A lot of those intermediaries have become fat, lazy, and myopic due to how easy it has been to hold onto their business up until now, for the most part they won't know what hit them until it's far too late to do anything about it.
