This document discusses platforms as positive-sum games that can include more people. It notes how civilization has expanded the scale of positive-sum games over time. Platforms drive network effects by supporting users, developers, providers and operators, and the more people included, the greater the network effects. Examples are given of open source projects with thousands of contributors and members. The vision is for ubiquitous and flexible cloud computing supporting multi-cloud applications that are portable and interoperable across a growing ecosystem.
