the world is already mostly digital and is moving towards becoming completely digital but none of it has anything to do with blockchain technology or cryptocurrencies. in fact the blockchain technology has a lot of potential but these are limited to certain areas, mainly a decentralized currency is the focus of the usage of this technology and not much else. in other areas this technology is not as good.
I believe were already on the digital world and its still developing into something very technological world. I belive crypto is just one of the few things that adds up to the digital world. It could build up the digital world with its capabilities and purpose but there is also other special things that could make our digital world now into much greater things.
