Putting hockey stick shaped lines on graphs with buzzwords on the x axis and dollars on the y axis does not a big idea make.
I am disappointed to see ideas that have failed to deliver for a decade like drone delivery (https://www.cbsnews.com/news/amazon-unveils-futuristic-plan-...) and 3D printing (https://www.economist.com/briefing/2011/02/10/the-printed-wo...) have a very long buzzword shelf-life, presumably because they are enduringly futuristic. First principles should tell us that most manufactured goods will never be 3D printed. There are entire fields of engineering dedicated to manufacturing processes, because the final material properties and cost of an item are affected by things like cooling rate, grain orientation, surface finish, tensile strength, and tolerances. 3D printing is another tool in the toolbox, not a replacement for the toolbox. I personally find them useful for ideation, but useless for creating finished products. It is worth considering that the entire market for 3D printers consists of rapid prototyping and Etsy knicknacks, and that it has been saturated.
