I don't think minimalistic design necessarily creates sameness. Hundreds of sites using the same handful of frameworks for ease of load and creation across platforms certainly does.
The point I was making was that sameness is a market effect, not a technological one. If everyone in the world started craving for Google Glass tomorrow and nothing else, everything in the world of design or systems architecture would trend in that direction in a reasonable amount of time. Trend in a sense wherein it is easily produced, etc. and other factors.
The market desire you describe is for clear, convertible content, not sameness.
Sameness isn't the value, it's a follow-on symptom of many, many developers taking the same short road to clear, convertible content via frameworks.
A case could be made for value in sameness, familiarity, but that's not the case you're presenting.
