I think the quote lacks the required context. He was talking about human DNA, not about programming:
>> Human communication methods are all buggy as hell :)
>Not to mention that they are slow, inefficient and ambiguous.
>But wht did you expect? The original authors of the code are long gone and maintenance is done by newcomers who are patching the code bit by bit. What you get from such a development model is pretty predictable: ~1 billion years old spaghetti DNA that no-one truly understands.
It's actually only funny if you see it in that context: "bit-by-bit" changes to the DNA (=mutations) etc..
But it's nice to see how similar human evolution and programming really are
