hahaha, I'm going to try the math on this.
Let's assume that the entire holographic matrix is based off of the human genetic code. That's 6 billion base pairs. with four possible bits (a,g,t,c) thats about 1.5 GB.
Now lets take the entire wikipedia database and multiply it by 100, and thats really conservative, of course. as of august of 2006 wikipedia was 400GB. 40001.5 GB.
Of course this isn't even close to an accurate portrayal, but its fun thinking.
