Introduction If we combine all the Wikipedias (https://en.wikipedia.org/wiki/Wikipedia:Size_comparisons), there will be 27 billion words, written in 293 languages, spread across over 40 million articles. By crowdsourcing knowledge and offering it for free over the internet, there is little doubt that Wikipedia has provided immense value to humanity. The project, unlike many others, successfully tapped into the open source spirit of the Web 1.0 and survived the onslaught (https://www.zdnet.com/article/google-knol-wikipedia-killer-or-knowledge-management-app/) of the walled gardens that sprung up as the web evolved. As the world’s most frequented encyclopedia in humanity’s history, it has achieved enviable success in its mission to democratize knowledge. So why is Larry Sanger (https://en.wikipedia.org/wiki/Larry_Sanger), the co-founder of Wikipedia, one of its harshest (https://www.vice.com/en_us/article/bnppw4/wikipedias-co-founder-is-wikipedias-biggest-critic-511) critics? What is his vision for a Wikipedia 2.0? And what has it got to do with the blockchain? In the latest episode of the AGI Podcast (https://singularitynet.io/podcast/), we asked Larry Sanger all of those questions — and more — for a fascinating and insightful conversation on knowledge marketplaces, decentralized curation, and finding the best of our knowledge.
