Thoughts on the Singularity and how Virtual Reality cannot replace Real Reality

Interesting piece on the Singularity by Rudy Rucker, famed sci-fi writer:

if you want to smoothly transform a blade of grass into some nanomachines simulating a blade of grass, then why bother pulverizing the blade of grass at all? After all, any object at all can be viewed as a quantum computation! The blade of grass already is an assemblage of nanomachines emulating a blade of grass. To the extent that you can realize an accurate VR world, the exercise becomes pointless.
Just as she is, Nature embodies superhuman intelligence. She’s not some piece of crap to tear apart and use up.
