Readers are debating why the Alphabet subsidiary's plans for a waterfront smart city were abandoned and sharing their thoughts on other top stories in this week's comments update.

"Unprecedented economic uncertainty" caused by the coronavirus pandemic has been cited as the reason why  Sidewalk Labs has abandoned its plans to create a smart neighbourhood in Toronto.

"Good riddance to a large-scale data-harvesting wheeze"

But Dezeen commenters are unconvinced. "Best news during the pandemic thus far," said Troels Steenholdt Heiredal. "Good riddance to a large-scale data-harvesting wheeze," agreed Bunker Mentality.

"The pandemic is a handy excuse," added Tyrannosaurus Rek. "But opposition and concern about privacy was widespread."

"As this health crisis is just temporary I wonder if it is the right move to scrap a project that's basically a playground for research,"  countered Zea Newland. "This is a missed opportunity to show the world how a smart city can enhance life."
