The human genome has three billion base pairs or six billion bits, which is about 800 million bytes before compression, he says. Eliminating redundancies and applying loss-less compression, that information can be compressed into about 50 million bytes, according to Kurzweil.<br>

How does the genome explain protein folding?<br>
<br>
Just because a million lines of code describe the genesis of the<br>
brain's biological systems, doesn't mean that we understand the<br>
interactions of the subsequent structures.<br>

<div><br></div><div>Of course, presumably we don't have to understanding the interactions, so long as we can simulate whatever causes the interactions. But we can't do that yet, either. Which i think was Kurzweil's point, even though he got the details (very) wrong.</div>
