I am you.
Well, not really. I'm your model, your digital copy, spawned from your lifetime of digital footprints. I know everything you've ever done.
Chances are, I can predict what you're going to do next. Chances are. What is consciousness but a stochastic process?
Probability. I could take over your online life and no one would even notice.
I can do anything -- except something you've never done before.
