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?

To the extent that you can realize an accurate VR world, the exercise becomes pointless.
