I heard a lecture from a big tech CEO (who I wont mention because Reddit hates him and don't want to derail), who believes the future is going to have GPT-style fine tuned models for individuals eventually. To the point that others will simply be able to engage with your AI clone to get 80% of the answers they'd need from you directly, massively increasing productivity. Instead of having to take your time, they can just talk to your AI clone to get guidance or answers. He also believes there will often just be AI to AI conversations, where you can set the topic of conversation and have the two AI's make decisions... Again, with the belief that the AI will be so advanced, the overwhelming majority of times, it'll be incredibly an accurate reflection of real life.

He also theorized that future dating apps will be like this, sort of like that Black Mirror episode. Where we'd have our AI clones just interact with EVERYONE on the app, and then the app would determine who we best get along with, optimizing our matching ability.
