We will use Grok 3.5 (maybe we should call it 4), which has advanced reasoning, to rewrite the entire corpus of human knowledge, adding missing information and deleting errors.
Then retrain on that.
Far too much garbage in any foundation model trained on uncorrected data.

Most if not all leading models use synthetic data extensively to do exactly this. However, the synthetic data needs to be well defined and essentially programmed by the data scientists. If you don't define the data very carefully, ideally math or programs you can verify as correct automatically, it's worse than useless. The scope is usually very narrow, no hitchhikers guide to the galaxy rewrite.
But in any case he's probably just parroting whatever his engineers pitched him to look smart and in charge.
