One of the problems of reading digital books (at least for me) is near-completely forgetting where a fact came from, and just remembering the fact. The source was a book on the future actually being likely to be good/improving from where we are now. My memory on the specifics is vague. I remember him saying they had lost fish hooks (maybe just some fishing technique in general?). And that further losses occurred in the migration to Tasmania, leaving the settlers there even further behind. I don't know what "Quadrant" references.
