This area is a concrete wasteland–just car-parks and abandoned lots–that's now going to be portioned off to more giant, glass condo buildings, and while Sidewalk's proposal had problems, it was focused on building something very different, community-oriented, without prioritizing roads.
Sidewalk really pushed the technology angle way too hard, and it was a clear overstep– most of it wasn't necessary for any sort of quality of life improvements, but many of the ideas like wooden 'skyscrapers' and de-prioritizing roads were exciting, now lost.
