What kind of hyper-social person would even have enough text messages to train a model? Not only do I send messages like twice a week at max, my tone is completely different depending on who I talk to. Not even my language choice is consistent - when my parents text me in russian, I reply in russian (via bad speech to text, I can barely write that language), but when my husbands parents text me in russian, I usually reply in german. Coworkers and friends usually get german, unless I’m quoting english memes or technical documentation and my husband and I text in 95% english unless german is totally necessary. Just explaining that constellation to an LLM would be super annoying haha
