Eliminating redundancies and applying loss-less compression, that information can be compressed into about 50 million bytes, according to Kurzweil.

It doesn't. So what?

When I was a kid I built some electronic devices from kits, I just followed the instructions. When I was soldering in a capacitor I didn't understand how it interacted with all the other capacitors coils resistors and transistors in the device much less the integrated circuits, nevertheless when I was finished the thing worked because I followed instructions. Understanding is for philosophers not assembly line workers. The great advantage of reverse engineering is that understanding is not necessary.
