This is a fun question! In some ways, this is already happening. You can create a 3D model of yourself. Microsoft has research that can synthesize your voice from samples of you talking. Adobe’s VoCo can also synthesize speech that sounds like you. There are also emergent products, like Replika, you can train by feeding them data about you and that in turn can mimic the way you talk. So, in a word, yes, sometime in the not-too-distant future.
