haha i like your post it really takes us to the future which is too near from now 3-4years. Every time i think in the potential of the Blockchain community and all coins together, it blown my mind.
You can image that every thing in your life could be on blockchain, thanks for the variation of all Altcoins and each one is specified in a particular thing.
Better futre.. Better Invest in All Altcoins.
Have a good day.
