> The content industries should have been the ones to invent LLMs
While exclusively-controlled LLMs would be mildly useful to them, the technology existing is dangerous to them, and they already have a surplus supply of content at low cost that they monetize by controlling discovery, gatekeeping, and promotion, so I don't think it makes sense for them to put energy into LLMs even if they had the technical acumen to recognize the possibilities (much the same way that Google, despite leading in developing the underlying technology, had vvery little incentive to productize it since it was disruptive to their established business, until someone else already did and the choice was to compete on that or lose entirely.)
You have to get ahead of the disruption that will destroy you. At least, if you care about longevity of your company. I realize this isn't always the case.
