Everything you type in your iPhone could be used to train a digital you

Everything you type in your iPhone, every feeling you note down in Journal, could give a future Siri (or another agent) every bit of data it needs to create a digital you.

The thought I had was that an AI agent could prompt you every day to ask you how you're feeling, or write a few things about a different things, and overtime it would get an idea about how you think. The more you type into it, the more you tell it how you feel, think, decide on things, the better it would get at being you.

A company could release this product now. Let it run for a year or two. Let it get better, slowly, steadily, till it is good enough one day. And then you have your own personal agent. Similar to how the Zoom CEO talked on Decoder about a world filled with digital twins.

Then I thought, this exists already. Apple Journal exists where, if you were an avid user, you would type out how your day went; how somehting made you feel, etc. They could use this data to train your digital clone.
