If you already know that your model contains falsehoods, what is gained by having a chain of provenance? It can't possibly make you trust it more.
A chain of providence isn't much different then that person having a diploma, a company work badge, and state issued ID. You at least know they aren't some random off the street.
If not, it's just a diploma from some random organisation off the street.
So, wake me up when you know how OpenAI and Google are cooking their models.
