But is this stealing the focus from things that could make a bigger impact to human life? Are there other better things we could be doing instead with the amount of energy spent in these areas?
Yes, including literally nothing. We could stop wasting all that power on reinventing worse versions of what we already have and breathing new life into old scams.
The scary realization though is that the problems that really need solving in our world are hard.
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.
