There isn't too much discussion when there's a new version of Photoshop, or VIM, or Django, or Wordpress, or countless other technologies (e.g. http://www.asciiflow.com/) and platforms that help with content creation. One reason I read HN is that these items usually make it here. It's easier to create content now than at any time in the past.
How many people built software before iOS and Android? A few folks scattered across huge companies that either built consumer products or provided services for those companies. Today, iOS has half a million apps -- somebody produced them. Arguably the 'consumption-only' device that you think has taken us a step backward has given tens of thousands of people incentive to produce something. Amazon's vision is for authors to be able to self-publish without going through the hassle of publishers, giving more incentive for people to produce. Whereas making movies was once a task for multibillion dollar studios, Youtube has enabled something like the Khan Academy to start earning money by producing content.
You cannot have better and better consumption oriented devices in a vacuum. Someone has to produce what the masses are consuming.
