> Good examples are probably Amazon and Walmart. Depending on your social stratum, the role that these play is probably equivalently profound in your life. And the core logistics behind both business [models] is predicated on a set of technologies and integrations with other related industries that is radically unlike what came before it. But we had Walmart in 1995. It was as awesome for poor folks then as it is now. > Other examples include the slow-boil but now nearly complete homogenization of the commercial landscape in the US. If you didn't grow up in e.g. the 70s or earlier, the ubiquity of a couple hundred brands and the insignificance of anything but large regional competitors (aside from in a few exceptional industries perhaps) is actually a very different and quite new reality. I remember people commenting about that exact phenomenon … in the 1990s. Both of those are, I think, good example of what I was getting at: things changed hugely from 1974 to 1995, but not nearly as radically since then.
