The key point — as far as I’m concerned — in this article about the DIYization of beer brewing comes in the middle of a paragraph:
Home brewing is part of a broad spectrum of DIY activities including amateur astronomy, backyard biodiesel brewing, experimental architecture, open-source 3-D printing, even urban farming. . . . Many of these pastimes can lead to new ideas, processes, and apparatus that might not otherwise exist.
Likewise with the DIYization of science: It will produce new ideas, solutions, etc. The Shangri-La Diet is an example.
