I was mostly agreeing with you. Sorry for the confusion. If I'd needed someone to be in direct contrast to, it'd have been fairer to quote chrisbrat:
chrisbrat is mistaking cause for effect here. The must-drive eat-shop-only malls (eg. Meadow Glen & Assembly Row) failed to renew themselves because their model had failed and been overbuilt, not that their model failed because they were no longer new.
The Atrium Mall in Chestnut Hill (1989-2012) was always new, but failed even when brand new and even after several cosmetic redos.
The problem was urban traffic is awful (we've doubled car ownership since 1970 but added basically no lane-miles) and that online shopping killed most small-box stores and every department store department except fashion & cosmetics.
Assembly is new the way that Rockefeller Center was a World's Fair sort of new in 1939. There's nothing inherent in its design (that I can see) that makes it unsustainable.
In fact, Assembly, by building lots of structured parking, has left itself semi-blocks that make sense now, but which it can easily tear out and replace with mixed use in the future as households go ever-more car-lite.
