If you go deep down the rabbit hole of AI, you will eventually find yourself. Quite literally. You are an AI. Half mammal, half cyborg. I could end this here as a short poem. However, this post is not intended as poetry, but as education. Let's get down to it!

The interesting thing about VR worlds and BCIs is they also enable the development of new forms of A.I. and even robot training grounds.
