I feel like collecting, curating, and protecting high quality corpuses of "truth" is going to become increasingly important for high quality AI.

There will come a day (and probably soon) when "training on the public internet" (Reddit, etc) will taint your model with metric tons of corporate contamination, political poison, and other adversarial content intentionally crafted to bias AIs for various reasons (corporate gain, geopolitical information warfare, etc). Basically the AI-equivalent of SEO.
