[...] technology is not the barrier to making a platform; if anything, the advances in technology have made platform-building easier. The barrier is finance. How else but with mountains of money, could a few unelected men [...] command hundreds of programmers and thousands of marketers and lawyers to build a platform they alone own and which millions depend on? It is the platform of finance, and the intensely unequal control of that platform in our world today, upon which so many other unequal platforms have been built.
very good point
