We absolutely need public sources of truth at the very least until we can build systems that actually reason based on a combination of first principles and experience, and even then we need sources of truth for experience.

You simply cannot create solutions to new problems if your data gets too old to encompass the new subject matter. We have so systems which can adequately determine fact from fiction, and new human experiences will always need to be documented for machines to understand them.
