I think it’s always been, we just knew that the effort needed to fake many things requires some degree of skill available to a few and was often expensive. But perfect fakes have always existed. This is why artists usually sign their work? What we will need today is to start signing things digitally in the same way, which I think will require very good, decentralized pki, unlike what we have with email. Essentially, different pki should work like dns, and find the pki for someone, and cache it., so that your signature works in china and the moon. Updating it should work the same way, the old one should always work and new ones should have the old pub keys appended to them so any public key can be used to verify all past signatures.
