In short: Yes, but it's not a problem. Consider the situation, say, 5 years ago. We all watched TV. That's consume-only; no user production involved. We all read books. Same deal. Radio, newspapers, etc. All the same. But, we all also had computers, and we used to them to produce, interact, etc. The point is that we used a number of devices, we did some producing, but mostly we consumed. Now, perhaps a few years from now, when newspapers, radio, etc., are all dead, we will do all this with just one or two devices. But we should still expect each individual to do a lot more consuming than producing. (Note: This is not to say I'm happy with the Apple/Amazon-runs-the-show model of computing. I don't own a Kindle, or an iPhone-OS-anything. Nor do I intend to get one.)
