I predicted it few years ago, we are headed towards a cash less society

That's the natural evolution of the economy anyways, optimizing energy, resources and usages, no waste, no trash

Money only just an agreement between parties, as long as we agree, then we don't need money anymore

Social contract, as long as you are part of the community (it'll end up being worldwide), you'll receive everything you need (universal basic income), unemployment, crime, poverty, diseases, all will disappear

Optimizing energy for finally sailing in space, and engage with space exploration, meeting with our advanced neighbors
