I think the interesting part is that he can be quite vague because the ecosystem is still being created. Projects are being added at an accelerated rate and doing a number of things many probably did not think about in the beginning of this journey. Whereas entrepreneurs could have been considered those that invested to create voting bots in the past, they can now be considered totally unrelated projects like @actifit or @steemmonsters! Would you have thought a trading card games would be developed on the STEEM blockchain two years ago? I think this is the vision that was set when it all started and given the social focus, the sky is the limit on what can be created.
