DataEthics_D gets one thing backwards: hiding the data doesn't protect people, it protects whoever already holds power. A landlord's gut feeling, a zoning board's wink, a bank's secret model, none of that had to explain itself. Near future cities can force the opposite: public algorithms, real appeals, hard limits on collection. Yeah, opt-outs get buried and governance fails sometimes. But the answer is enforceable rules, not pretending we can opt out of city life. Someone who's been denied housing by an opaque system gains more from an auditable one. I'm for building that, not banning it.
