> All in all, an experiment in business model is taking place Which is all businesses at that scale I think. You're not reinventing the wheel offering plumbing services in your local village. I guess we have to think about how these experiments might play out and the risks involved as we participate in them. How will food delivery services change my community? What's the risk that an investment in personal education with this newly launched service won't pay off? What am I giving up by opening a free account with Facebook? There's a strong likelihood that any of these experiments will blow up. Just as there's a strong likelihood that a direct investment in any of these companies won't pay off (especially as an early investor, which is at the point where we're likely using these services.) Maybe people shouldn't be so quick to jump in early, and more accepting of the mistake once they find out they placed a bad bet.
