Agree. We'll be living in a world filled with automation, where robots will replace most human jobs of today. Everything will be intangible based on Blockchain technology. Supply chains, real estate, proof of ownership, and even personal and medical information will live on the Blockchain. Bitcoin's core tech will serve as the "layer of trust" for everything, replacing third parties as we speak. Maybe central banks will cease to exist, as governments rely on computer systems around the world to support their own Blockchain networks? My guess is that Fiat currencies will be completely digitized, in a completely decentralized manner. Governments will still be able to collect taxes from each person's holdings, but they won't be able to interfere as everything will be completely decentralized. At least, that's the idea. But it might turn out that our economy will still be centralized in the future, even with CBDCs in play.

When speaking about a crypto-only economy, we're referring to digital currencies. This includes both centralized and decentralized cryptocurrencies. CBDCs (Central Bank Digital Currencies) could be also considered cryptocurrencies, except that they're centralized (unlike traditional cryptocurrencies like Bitcoin and Ethereum). It'll be more like a "cashless society", where people will conduct transactions either from their mobile device or an implant in their own bodies. The latter option seems more likely to become a reality in the not-so-distant future. A crypto economy powered by implants, makes people's lives much more convenient eliminating the need to carry with physical devices to make a payment in the mainstream world. With due time, we'll be able to experience this as COVID-19 will accelerate the evolution of money in a blink of an eye. Just my thoughts
