Still applicable, and will be applicable for a while. I mean, some economists have written on this as early as 2003, so this is not so hot news to those who followed recent developments.
I think my unique insight (which those others did not publish) is that finance and capital itself is losing relevance as the fixed capital industrial age dies.
I am asserting that storing money won't be as valuable an activity any more, because top-down money can't buy knowledge. Unlike manual labor, knowledge is not fungible from person-to-person, thus it can't be bought. It spawns from accretive, bottom-up activity.
