I think this paragraph from Nature’s article is very relevant:

The company has not revealed all the precise details and steps of how it did this, nor the name of the AI system that achieved the result

Ah yes, yet again an AI company achieves a great thing “by AI” with a perfectly opaque model in a perfectly opaque way. Why don’t they show their users how to unleash the full potential of their product? Reproducibility or GTFO.
