Blockchains and AI are complementary technologies;
And will be the most relevant in the upcoming decade.
With the massive improvements in AI,
AI-generated content will become indistinguishable from original one, which creates a far greater authenticity problem.
This requires a robust and sound solution;
digital signature schemes and a trustworthy source of information (permissionless blockchains).
This of course carries benefits such as the eradication of black mail, as no content – even if authentic – would be considered as such without the concerned party's signature.
