One of the aspects of SMTs I can appreciate is that they act as limited-use flexible contracts. This means we can see the benefits that some of the other smart contracts platforms have seen, but at the same time there is additional safety and security to keeping such contracts limited in terms of programmability.

Because, they are limited, I don't see Steem taking over the world. But it doesn't have to. What I can see is Steem becoming the backbone of internet content across the web, which given that the economy is moving more and more online means promising things for the Steem token.
