Besides the personal AI assistant another form of tool the AI development can bring us to help manage our digital life is a digital twin. When the language model can access all your digital communication it is able to learn your personal style of communication and provide more natural answers that will sound more like you.
A model that is fine tuned on users chat and mail history is able to create automated answers that don't sound like generic answers but actually feel like it's the person themself providing the replies. This can hugely help managing our digital lives when you don't have to spend time writing replies to all the messages you receive.
This too can be taken into a level of automation where you don't even need to read and reply to all those messages manually but it's still a good idea to not take that final step and let the twin answer all the time on it's own but just provide suggestions you can still verify and possibly edit before sending those messages out.
Ultimately these tools can lead to a world where our digital twins are just autonomously interacting with our AI personal assistants taking care of our digital lives without much interaction from us, just providing summaries of what's going on and trying to fulfill our needs.
