I see it from the perspective of someone working at a fast-moving, Silicon Valley-based software vendor. In that context, I don't see a lot of appreciation for history, in the day-to-day basis.
But it's not because people intrinsically don't care about it. It's more about our daily lives. We not only have to do what we all have to do, but we also have to keep up with the latest if we want to survive here. That line of thinking constantly pushes us forward, and doesn't reward looking at the past.
