Money has already evolved several times in human history and will continue to evolve in the future. We started from animal skins to beads and feathers to precious metals and gems to paper and cards. And obviously the next phase has already begun from the creation of bitcoin. This is unstoppable.
I agree with that, well we started with just stick and stones. As years go by people tend to find ways on how to make everything convenient. Then, there comes fiat money. But, as we progress keeping your money is becoming more convenient, there's the plastic money. And, now we even have the cryptocurrencies. Who knows how money will be like in the future.
