Could you please expand on that?

I can try. Amazon sells physical products, while Facebook sells eyeballs to advertisers. This is how both businesses are setup to make money, at least at the days of IPO. While with Amazon you use it because you want a product, with Facebook you do not want to be plastered with Ads, but you have no choice.

Amazon is a solid horse with no "kill me" obstacles on its way. Sure in 150 years you will have a machine a size of your fridge and you download blueprint from internet and the product is being 3d-printed for you, but since we not there just yet everyone needs products that Amazon offers and shift is towards selling stuff online. Mobile movement is to Amazon irrelevant while it may kill Facebook.

That's for start.

So, you are saying that in the future, Amazon will manufacture and sell blue prints and 3D printers? :-)

Better that than pushing legislation to ban 3d printers because they can infringe on copyrights

Agree for the most part.. though 20 years and the size of a toaster oven is probably more accurate.

As long as anything you plan to render is the size of a breadbox or smaller.

+1. Uncle Wiki says it must be an amazing book (that I've never heard of). Thanks for pointing out!
