While the comparison between Wikipedia and Britannica is certainly cliche, it’s still extremely useful. Not only does Wikipedia offer a much more more exhaustive, complete and inexpensive encyclopedic experience than Britannica, but is also offers us an open source software solution called MediaWIki, which runs Wikipedia, that is also used by millions of people to create knowledge bases for individuals and groups around the world. Therefore, Wikipedia doesn’t just offer us an a free encyclopedia, it also gives us an abundance of software tools for organizing knowledge, whether that information fits into the Wikipedia’s definition of knowledge or not. Similarly, blockchain-based technologies (including Bitcoin) not only offers us a useful and inexpensive mechanism for exchanging value, it also offers us an abundance of software tools for building our own monetary systems, whether they fit into the conventional finance’s definition of money or not.
