Only when I think about other industries as examples. In theory the more people fussing around some industry, the more tools they create for it, the more possibilities there are and so more money can be made. That's been true for scientific and technological progress overall, but individual industries stagnate. I understand the feeling, you're out of ideas or whatever, but there are actually more possibilities now than there were when Googleface was starting out, in theory. In practice industries stagnate for non-technical, social reasons. Too many people join, create too much fuss, the best people might leave and create a boom elsewhere.
