I was wondering why this sounded familiar and it's from 2011. Here are various things that have been invented along the same lines as Bret mentions.
* https://dynamicland.org/ - Bret Victor's vision, looks really cool
* Kinect was released (November 4, 2010) a little before this article and presented another vision of future, but the market didn't think so
* Oculus now detects hands and I'm pretty hopeful this will add more gestures and similar gait detection will be huge for interfaces
All in all, the incremental changes are starting to look more like what Bret is suggesting rather than purely "pane of glass"
