I won't miss (suburban) malls (shopping centers). I was never a mall rat, so maybe my perspective is skewed. That said, why not repurpose dying malls as living space for: homeless, hackerspaces, and those in more prime locations, raze and use the land to make into condominiums --malls typically have good transport connections. Make use of the land and buildings. That said some malls are built with expiration dates of 30 years or so, it would seem.
