Imagine your memories, way of thinking, and who you are being saved into a computer system. Not as a backup, but as a fully conscious version of yourself. Without a body, but with a mind. Sounds like science fiction? That’s exactly what mind uploading to a computer is. It’s an attempt to create a digital existence that can last forever.

In a virtual world where physics operates on different principles, a digital consciousness could eat virtual food, fly, travel to planets, or pass through walls. 

Limitations? Only those imposed by technology and the current state of knowledge. Associate Professor Dobromir Rahnev from the Georgia Institute of Technology’s School of Psychology does not rule out this possibility.

“Theoretically, mind uploading is possible. However, we are currently very far from this goal,” he writes in The Conversation.
