Web3 and blockchain are both an ideological and technological framework. Rather than holding anything back, they're originating and introducing a new way of looking at both personal data and how it's ingested and interpreted by web services.
All the crypto criticisms, the scams and rugs and mlm schemes; these are all characteristics of capitalism first, technologically implemented.
Where Web3 works, in the DAOs and decentralised governance systems, in the melding of decentralised tech and decentralised authority over it, that's where Web3 will flourish.
As humanity takes on the task of redressing the effects of capitalism, this ideological framework will guide our social development in the same way the blockchain is now reinventing software development.
