Also: I think many more product types could target smaller niches through some auto-scaling like service. For example, let's talk about food. it's possible to imagine Amazon starting a cloud for manufacturing food, where you send the recipes of what food to make, and you get a batch of it made(maybe not so large), and this gets distributed/sold via Amazon's grocery section. Same for restaurants, you upload you recipe, and some chain restaurant makes your food and give you royalties. And of course it could happen to clothes(already with printed t-shirts), electronics, shoes, etc. Maybe even houses, if housing gets done at a factory, modular fashion, using a set of standard blocks and software verification. And there are all kinds of new technologies, like hyperloop, bio manufacturing, etc - that would require building a lot of infrastructure. and the fastest the rate of change goes up, maybe infrastructure we'll get refreshed faster. And clearly we could use more teachers. Or people at command centers for self-driving cars.
