All advancement, leaves something behind. Every innovation replaces something.
This was the cherry you need on the pie. Old things lay foundations for new and better things to arise. We only hope is for the future betterment. Nothing detrimental. Hopefully cryptocurrency will send us there
I think the combination of crypto and blockchain will open up a whole new world of innovative possibility that we can't imagine fully yet. It will be fantastic to see what happens when there are millions of coders working on tens of thousands of projects with new tools in their hands.
