Questionable "Unresolved Disruptive Technologies" 

Some of the examples of "unresolved" technologies promoted as disruptive cannot honestly be considered "unresolved".  The most glaring of these is "e-commerce vs. physical shops".  It is absolutely clear that both e-commerce and physical shops are completely entrenched in their own respective niches, and while there is a lot of competition between them in some areas, the idea that either one could entirely supplant and eliminate the other in the forseeable future* is lunacy.  Similar arguments apply to "free / open-source vs. proprietary software" and "Internet Video on Demand and IPTV vs. Advertising supported broadcast and cable television".

The examples of "Music downloads and File sharing vs. compact discs", "ebooks vs. paper books", and "VoIP (and VoIP over 802.11) vs. traditional telephone and mobile phone service" are much better examples of "unresolved" potentially disruptive technologies.

"forseeable future" in this case refers to the current world we live in, free from instantaneous teleportation, William Gibson-style "simstim", and other similarly sci-fi developements.
