You brain is incapable of it because it is wired for linear thinking. We are not designed to think exponentially and that is what we are going.
Decentralization provides true exponential possibilities. Like on STEEM here, anyone with the know how can create an app and put it on the blockchain. At the same time, the same person can create a token with it and have a currency tied to that application.
This can be anyone in the world.
Where did that possibility ever exist before? Truly amazing.
Yup, all the possibilities and opportunities seem to be endless! Decentralization FTW!
