Yes that's is correct, for deep learning, as the magnificent 7 stocks have enough datasets for most of their projects and they can use transfer learning to leverage existing datasets for new projects, except for search/social media which requires constant human model evaluation. Unfortunately google withdrew all their projects including Yukon, which was the big one requiring ongoing human annotation, facebook has mostly withdrawn Uolo - facebook's version of Yukon.

LLMs require RLHF for the next few years. However it's highly likely the human labour business model for LLMs will turn out similar to deep learning. And appen does not appear to be having success in the generative AI industry.
