I mean, 90% of large cap investors have underperformed the sp500. It's not about optimal returns, it's about diversification and portfolio risk. The Saudi's want some of their money in things that aren't correlated with oil, and pretty much everything in the physical word is. Technology is one of the few things that may even be inversely correlated.

That's assuming that the Saudis are being rational with their money. Given that they are currently trying to build a city that's a straight line[0], and a "shape based" floating octagon city[1], that assumption might not be correct. It's entirely likely that the real answer has less to do with Softbank's performance and their need to diversify, and more to do with MBS liking Masayoshi Son.

The line one actually looks brilliant. It has the appeal of letting any new growth easily happen and keep transport options simple. Though most likely there will be uneven development even on this design.

It's genuinely the dumbest city design I have ever seen, and it makes transport an absolute nightmare assuming you're interacting with real technology and not magic.

Cities are generally round for a good reason. You put the important stuff in the middle and your average transit trip remains as low as possible. Straight lines do the opposite, as you guarantee that each new resident is in literally the worst possible position for transit possible, and you over tax the center’s transit in order to move people to the ends of the line.

Oh, and consider the cost for things like sewage and water. They’re a bit component of a city’s cost, and here they’re laid out as inefficiently as possible.

May be. But think not about the utilization or optimization for a moment and focus on the maintainability and buildability aspects. Something that looks this regular probably be both built and maintained through pure automation. I mean self driving is super simple in this layout (as they mention their transport is automated). Compare the same to the ever expanding cities that quickly run out of central space and end up having a premium center and poor suburbs.

Obviously line is not the only thing that can provide these benefits. How about a large square or circle with the center purely reserved for green space. Anything beats the shitty cities we have today where people stay outside because they cant afford the rent and have to travel towards the center for work.
