Top 10 disruptive technologies for the next 4 years

According to Gartner, the top 10 disruptive technologies in the next four years are:

* Multicore and hybrid processors
* Virtualisation and fabric computing
* Social networks and social software
* Cloud computing and cloud/Web platforms
* Web mashups
* User Interface
* Ubiquitous computing
* Contextual computing
* Augmented reality
* Semantics

I personally think that each of these technologies is already here or is in progress. The most interesting ones to follow are Semantics and Cloud Computing.
