I'm really looking forward to being able to use a personalized LoRa on top of a GPT-4+ class model. I want to be able to train on all of may writing over the past few decades and interrogate the history of my ideas, and I think this would be tremendously valuable for writers of all kinds. Heck, think of the value of training (with their blessing) on something like /r/AskHistorians, or other deep-dive, high quality fora.
