Disillusionment

First word art time period is equivalent to the Peak of Inflated Expectations, because technology and art in that area are not well understood and thus could not be judged by existing standards, they become idealized with too much hype, thus causing the Peak of Inflated Expectations. On the other hand, last word art is equivalent to Plateau of Productivity, where rules and understandings are now grounded in reality, so people can start producing them en masse.

I prefer to start on new technologies after the initial wave of hype and idealism has passed, so my interest lay somewhere after the start of the Slope of Enlightenment. This would be equivalent to being somewhere near the start of last word art.

Schulze prefers Trough of Disillusionment because it provides the perfect balance; we understood enough about the technology to not be misled by idealism, so he does not have to spend time personally conduct experimentation, yet at the same time there are plenty of opportunities that can be taken before the bandwagon rolls in.
