The OLPC thing is a useful lesson in product design though. It wasn't really a product, it was a mandate about what some people thought others should do, and now instead we have netbooks, the android ecosystem, tablets, and everything else. If someone in the world wants a laptop over other immediate needs, they can get one. Juicero I think had the same problem the rest of juicer market had, which it was a niche product for a nexus of people who both had an upper middle disposable income and thought it was a good idea to convert fibre rich foods into insulin spiking sugar water. Jibo's robot without a purpose was existentially pretty accurate, but they discovered nobody wants that kind of uncanny reminder of the absurdity of their existence hanging around. I joke, but a well aimed joke can destroy a brand, and having funny people around to take those shots can be company saving.
