Eventually our kids aren’t even going to know how to pay with cash or plastic lol
There's no reason to think that the concept of money won't completely change over another one or two hundred years. It's obvious it means something very different already but our caveman brains are having issues breaking away from 'money means so much thing...' but WHAT is money at this point? Monetary values, indeed the very definition of money will have to completely change in coming years. Think of us in 800Ad in the middle of what would soon be Europe and trying to grasp what 'economy' and 'money' looks like now. Everything changes.
