Decentralized Woo Hoo
I think this is a fair criticism to a limited extent, the crypto world is full of useless memecoins that don't have value beyond serving as gambling games.However some people interested in and working on blockchain and related technologies are pursuing ambitious goals that could reshape the economy and politics in ways that makes them more open to participation and "strongly typed"/formalized. Achieving these goals is not the same as "decentralization" but more about a concept where you start from a decentralized and open base (blockchain) and build structures atop that base that are appropriately balanced between centralized and decentralized.This is all very ambitious and may fail utterly and completely. But if it does succeed there will be a period where people have wild ambitious visions about what could be while the technology progresses to actualize those visions at what appears to be a slow pace.To provide a specific ambitious vision: you could have a world where appropriate taxation of a transaction is built into a smart contract and everything from deciding on how to spend that tax money to the project management for the efforts those tax dollars fund is conducted in the open by people who have achieved various types of stakeholder status. Actually creating a system that allows for this and doesn't have tons of other problems will take time.
