I appreciate the authors sentiments but I missed perhaps the most important one to me. Crypto has really re-invigorated interest in DIY/Tinkerer/random projects with no real purpose. These may appear pointless externally, but internally to the ones working on them they are incredibly fun, educational, and sure, potentially profitable. When industry / tech is in this chaotic phase, often the major benefit is figuring out what doesn't work, what fails, etc. If things were easy, everyone would do it, but when it's hard to get right, amazing innovation can happen along the way. Don't discount the random meandering towards solutions.
