## Nauti's Take

The AI industry talks a lot about safety, but its own supply chain is clearly a blind spot. Having training data – arguably the most valuable asset after model weights – sitting with an external vendor that then gets breached is not bad luck, it is a structural failure. Meta pulling the plug is a reaction, not a solution. Any AI lab serious about security needs to audit data vendors with the same rigor it applies to its own infrastructure.
