This is kind of strange given that the article isn't really about investing at all. If you can cut through the Friedman word salad his point seems to be "a 401(k) world requires you to learn much more about investing in yourself."
This article is, like so many of Friedman's, basically garbage. I guess he's saying that like you need to figure out what the best 401(k) investments are, so too do you need to figure out how best to shape your skillset for the market? I can barely find a thesis in this article other than "things are changing due to technology, some of this is good and some of it is bad."
It's possible, though, that the next six months will be critical.
