He does address it to some extent in that he's very pessimistic about the future. While I am quite enamored of his data and general skill as a researcher/writer, I choose to be a bit more optimistic about the future. If you go back and read some publications from the late 19th century any of the same concerns over job availability and mechanization appear. It is possible though, that we're past a different sort of tipping point now, and our robots will have a greater impact than the past's factories.

While I enjoy thinking and reading about these things and trying to piece together data into global narratives, I'm also realistic, we can't ever 100% know what's coming. I will try to remain upbeat about the future, enjoy what I have, and strive to put myself into positions to create clearly positive value for the country/world around me, no matter what the overall picture looks like.
