When you look at the DNA of a creature it is filled with all kind of stuff that we consider junk and we have no idea what it does. But then some new disease or predator shows up and it turns out that DNA had a use, but you could not have predicted it before hand.
The issue with knowledge is it's really hard to know what bits of it are going to be important in your future. Learning powerpoint probably put food on the table of a great number of people, it turns out our economy had a lot of places for that, and seemingly less, or less new jobs that wanted a deep knowledge of mathematics.

But that’s really the opposite of τέχνη, isn’t it? It’s an emergent phenomenon rather than one guided by teleology or at least by deliberation.
