So the article talks about three concepts: “Driverless rooms”, “Lego skyscrapers” that are powered by smart contracts that these driverless rooms park at, and “decentralized cities” that result because these rooms can rearrange themselves on demand.<p>We can already have a “driverless room”; it’s called a Winnebago. Most prominent politicians, musicians, and celebrities will have well-appointed RVs that carry them around. Even if you take the driver out of the equation, logistical issues abound: Where do you do laundry? What about plumbing? Where do you put out the garbage? I am reminded about that episode in “The Office” where Dwight crams everyone into an overcrowded bus and has them do work there.<p>Second, the article complains about overproduction and waste, but the proposed solution is to create skyscraper-sized parking lots? Even the picture that is supposed to idealize this shows the lego skyscraper half-empty. How will Bondi Beach look when this monstrosity looms over it?<p>Finally, moving things around isn’t free. Yes, solar energy and electric cars means that it’s renewable. But doesn’t mean it’s unlimited. We are going to dedicate a large amount of energy generated in moving “mobile rooms” around 24/7 for lots of people. That power still has to come from a power plant somewhere. Life isn’t like AWS; you can’t just spin up a solarpanel2.large.<p>I know this is essentially a piece of utopian fiction, but there are glaring flaws in this just aesthetically, let alone with other factors.
