"It simply outlines the plusses and minuses of having our apps and data on someone else's computer. It also discusses current trends in decentralized and recentralized data and applications, the inherent dangers in deploying – or not deploying – data to someone else's computer and then makes some assumptions about where apps and data will end up in the future."
