Human hours are a proxy, and the proxy is bigger than the real thing: the two Ego4D sets alone hold more hours than the largest open robot dataset. Whether they count toward the ten million is the open question on synthetic and proxy hours. Their licenses differ set by set, and one of them is a draft.

  The report's framing, per the Xinhua summary: a 55 billion parameter model needs about 1.1 trillion tokens; if all of it came from real robot data, that is roughly 21,200 robots working a full year, or effective data at the ten million hour scale.

  GDPR and the EDPB video guidelines: footage of an identifiable person is personal data; it is biometric only when processed to identify. Workers are owed a lawful basis and information, and consent is a weak basis at work.
