The article's example of the Apple store as a model of a retailer that "just plunks a glass cube on busy shopping streets" is pretty clueless. Most Apple stores are in malls!
I think the issue with Malls is that in 1980-something, your choices were dying downtowns, department stores or the Sears/LL Bean/whatever catalog. For food it was local places, McDonalds/Burger King/Wendy's. The mall offered more choice for food and retail.
Nowadays, the traditional mall retailers are all consolidated and offer similar stuff. Why hang out in a food court when you have a dozen fast casual restaurant choices outside the mall?
