The input data for your own analysis lies in the conceptual arbitrariness of "important knowledge" and "useful knowledge". These are the foundation of your argument. If their validity is in question, as I propose it is, then all the arithmetic in the world will not hold it together.

Nope. If you'll look at the math, you'll see that I said "important knowledge" ranges somewhere between O(log(raw information)) and O(raw information). Important knowledge = O(raw information) means we do not make any distinction between raw information and "important" information.

the evolution of living systems and the evolution of technology (with which it is contiguous) are components of an ongoing natural process.

Some of the ancients would have said that human inventions and nature are fundamentally the same, since nature is the invention of God. Now some people say that technology and evolution are fundamentally the same, since humans are part of nature.

Whatever. I just want to know if the curves match.
