That's my optimistic forecast for what happens after the current speculative bubble pops. We'll be left with e.g. universal sign-on via crypto wallet that's not owned by any corporation and can be used for cryptographic signature / voting / &c. We'll also have increasingly robust decentralized infrastructure like zero-knowledge rollup L2s on top of Ethereum to make increasing complex decentralized applications. The money making stuff is about as vacuous as everyone seems to think but the substance it's attached to is a movement away from walled gardens and towards increasingly empowered individuals.
