"The Master Switch" is a good book to read. If we apply the ideas from that book to the blockchain space, we'd expect large players to eventually dominate, as Apple,Amazon,Facebook,Google... dominate today. I.e. you might expect companies (such as the Consensys conglomerate that invests in the Ethereum ecosystem) to dominate if the space continues to grow. One possible counter to this line of thought is projects such as Ethereum, Augur, 0x, and Gnosis have non-profit foundations behind them and are working on protocols and APIs and thus do not have the same for-profit motive to grow large.
Wu also has a new book "The Curse of Bigness" that I recommend: https://www.amazon.com/gp/product/B07HRLQSLG/ref=dbs_a_def_r...
