Theyea the reason we never went forward with depthscrapers was kinda obvious instantly right? Stuff falls down. On a skyscraper, things fall down or off a skyscraper. When you have a big pit in the ground......well?
To be clear, in the event of fire, some people would have to CLIMB dozens of stories of stairs to get to 'safety' on the surface. Then survivors would wait for firefighters to arrive and toast marshmallows with them because they wouldn't be able to do anything about it either. Filling the hole with water would just be a waste of water.
Thanks to your videos about the city, I've become absolutely fascinated by it. It started as inspiration for my fiction worldbuilding, but now I'm just genuinely interested in the city's story as a whole. So thank you for making these videos!
IMO- In the US, any subject matter surrounding bathroom/restroom activities is easily turned into a joke, used to embarrass one, along with all kinds of other social stigmas that are attached to our natural human activity. Maybe it’s this behavior that causes us to have a lack of respect for public restrooms. IDK spit balling. And yes access to a decent facility is a basic human right; doesn’t have to be perfect with the latest and greatest shiniest go faster, but it should be clean and functional.
The only people worried about people turning on them like that are people who legit would turn on people. Part of the reason why billionaires love the idea. They know they wouldn't be powerful in a catastrophic situation and thus would rather hide away than admit defeat.
How many abandoned open mine pits are on earth? How many of them poison the surrounding environment? How many of them are considered "too costly" to fix? This would appear to be a solution that pays for its self while bringing the land back to a place that could be profitable for decades to come. Water management would be a significant and constant consideration though. This would be especially true after an earthquake.
