You obviously didn't read the article...
Your point is literally exactly what that article addresses. The ONLY way to verify that anything is true now that we're entering The Great Disillusionment is to have cryptographically verified who it's coming from, when/where/by whom it was created, AND who else trusts the source of that information. Even verified senders may still may be sending corrupted information, but you'll at least be able to know who it's coming from. So, that's also why the cryptographically verified Knowledge Vault and Credentials are essential, because AI can and will corrupt truth regarding history, the present, and people's skill sets. That's why the Web of Trust along with the Nostr ID being established as a template with the Satnam "Identity Forge" and the "Knowledge Vault" being built by the Citadel Academy must work together to establish Verifiable Truth in a world where digital truth has been corrupted.
