I just took a quick look at recently released EOS.IO Technical White Paper. My first impression is that initial version of EOS will be deployed as minimum viable product in accordance with LEAN STARTUP methodology.
Based on the list of core features and functionalities I conclude that central focus will be migration of Steem and Bitshares on EOS platform and nothing more.
After that I expect constant adjustments through implementation of LEAN STARTUP Build-Measure-Learn feedback loop and zoom-out pivot in order to deploy the widest range of blockchain DAPPs.
I don't know if Dan uses LEAN STARTUP but I'm sure it was considering a similar fashion.
I would like to see Ripple, Factom, Symbiont and Golem among others running on EOS platform.
