I think a very important part of this will be when people don't even realize they're using blockchains and they use dapps/dev projects because it is useful, fully functional and rewarding (tokenized).
This will be the point that people are getting on the bus, paying on a blockchain and have no idea what a blockchain does. Mass adoption.
Steem's capabilities (tx speed/ no fees) make it a great place to build and when vibrant communities are added into the mix it makes it very attractive. Hopefully when/if smts are released people will see its real potential.
The no fees is going to potentially be a huge advantage for Steem once transaction volumes increase significantly across all the chains. Other chains are likely going to have to decrease their fees or make them free to compete.
