When will lonely, elderly people start to talk to LLMs on a massive scale? Is this already happening?

It can be extremely tiring to listen to stories of mildly demented people who struggle to string thoughts together and they don't want to be a burden neither but they want to talk more than others around might have time to listen.

I'm reluctant to put these thoughts out as I might come across as being cruel but I think, some would flourish with such an AI companion that never gets tired listening to their stories, especially if it was tasked to do something with the information collected. Not "Grandma, talk to the bot, please. I have to work" but "Grandma, I'd love to have a book written about your exciting life!"
