Same question I suppose. The parent diagram featured both the hype cycle and Moore's chasm. Do they both operate on different timescales or are they usually a decade end-to-end?
Honestly? I think it's similar to a lot of pop-business constructions. Post hoc, and it sounds insightful enough to inspire pattern matching, but doesn't actually have any real explanatory power.
Anecdotally, I have heard people applying different timescales for the hype cycle for different technologies. Makes the pattern that much easier to match.
