Everyone assumes that designing a product for mass production must be easy since "industry" is a part of the "old economy" and thusly must have been so figured out that anyone can do it. The reality is that the past century of modern manufacturing development hasn't resulted in amazing amounts of simplicity just the same as how the "tech" world has only become more complex. The difference is one has a century of exponential complexity growth behind it while.the other has ~30 years of complexity growth in its modern era.
