How valuable is 70 petabytes of temperature sensor readings to a commercial LLM? It is in fact negative. You don't want to be training the LLM on that data. You've only got so much room in those neurons and we don't need it consumed with trying to predict temperature data series.
We don't need "more data", we need "more data of the specific types we're training on". That is not so readily available.
Although it doesn't really matter anyhow. The ideas in the document are utterly impractical. Nobody is going to label the world's data with a super-complex permission scheme any more than the world created the Semantic Web by labeling the world's data with rich metadata and cross-linking. But especially since it would be of negative value to AI training anyhow.
