short questions: does the public "need" these "high-cost developments"? Is there any advantage for the public or is it all about Alphabet having a giant playground where they don't have to deal with pesky customers but can have their small herd of citizen-sheep they are not directly accountable to? Is such a village more sustainable than just taking the same building without tech?
