I found this part of Koolhaas's quote quite interesting:
"Convergence is possible only at the price of shedding identity. That is usually seen as a loss. But at the scale at which it occurs it must mean something. What are the disadvantages of identity, and conversely, what are the advantages of blankness?"
The question doesn't need an answer, it's just the exploration of the idea without judgement that I find interesting.
