Content is cheap - AI will drop the costs to zero.

Truth is still expensive. 

This is why blockchains will have an incredible decade. Stake weighted consensus and markets are one of our best tools for determining truth.

Blockchain truth is not content truth tho.

A valid block can contain lies.

It doesn't contain "true things" it contains attestations, like "@rsa.eth says that this thing is true". This means that identities can build or wreck their reputation in a verifiable way.

It's not that everything attested to is true. If disinfo is attested to, the truth is that someone attested to it.
