And while this nice open collaboration is a nice idea, its up against much more than the cost of hardware. The FCC will likely clamp down hard on people trying to setup an open wireless network. Even data scientists are going "WTF?" at the insistence that blockchain is going to solve any of the things it claims it will, and that the decentralized nature has already shown serious problems (and if you think it enhances security then...just wow).
At least that's what I thought until I went to a startup meeting in a local incubator. Guy gets up and talks about how blockchain (and his startup) is revolutionizing his industry. His problem is one that is clearly better solved with a traditional database; it would be easier, cheaper, and more performant. Smart guy but clearly spewing bullcrap. I had no idea why he reached the conclusions he did until the end of the meeting when the gentlemen behind me raised his hand and asked if the speaker was taking new investment money as he represented a small group of local investors wanting to get into blockchain. Now I realize I've spent the last 10 years working on the wrong skills, I should master the art of bullcrapping.
