Personally, I find it somewhat amazing that you put Demis on that list given that he, himself, on very good accounts that I have, explicitly pushed back against natural language processing (and thus large language model) development at DeepMind for the longest of times and they had to play major catch up once it became obvious that their primarily reinforcement learning-oriented and "foundational" approaches were not showing as much promise as what OpenAI and Facebook were producing. Do not get me wrong, what he has accomplished is utterly amazing, but he certainly is not a father of large language models.
