Kinda getting an Eclipse Phase sort of vibe. As such I must ask the following.

Have AI hit a level of humanity? What are relations with humans and AI?
How common are artificial bodies? Do most people implant their minds into such a shell for various purposes? 
And have animals been uplifted in intelligence?
What is the state of Earth? 
Etc.

And just so you have an idea on Eclipse Phase (if unaware)

I would suggest giving it a read, well the setting, though the mechanics are neat and also worth reading.

Cheers.
