Greg Isenberg recently wrote about what he refers to as the fast-foodification of everything — including cities. His arguments are that (1) we have reached peak sameness (Toronto is largely indistinguishable from, say, Sydney) and (2) the best brands and companies going forward will be local, unique, and community-driven.
I don’t know how to assess whether we have reached peak sameness, but I do know that, whatever we are experiencing right now, is at a minimum 100 years in the making. The International Style (of architecture), which emerged after WWI, is exactly what the name suggests. The intent was to fashion an approach to architecture that worked anywhere in the world. Location, climate, and context were all irrelevant.
This approach has been widely criticized for the reasons you might expect and for the reasons that Isenberg outlines in his post. But sameness is not exclusively the result of European architects who wanted to eschew ornament and local flourishes. As the world continues to globalize and become “smaller”, there is an inevitability to this growing and continued sameness. Business wants economies of scale.
But there is no question that, more than ever, people are craving unique and local experiences and places. And if you can create that in our globalized world, you are going to win.

Jerry Neumann's recent blog post on the "taxonomy of moats" is a great summary of the ways in which companies -- and perhaps even cities -- can protect themselves against competition.
Here's an excerpt from his introduction:
Value is created through innovation, but how much of that value accrues to the innovator depends partly on how quickly their competitors imitate the innovation. Innovators must deter competition to get some of the value they created. These ways of deterring competition are called, in various contexts, barriers to entry, sustainable competitive advantages, or, colloquially, moats. There are many different moats but they have at their root only a few different principles. This post is an attempt at categorizing the best-known moats by those principles in order to evaluate them systematically in the context of starting a company.
And here is his taxonomy of moats. He identifies four main sources:

As a sidebar, consider how this might also apply to cities.
Scale, for example, matters a great deal. We know that as cities get bigger, people tend to walk faster, have broader social connections (the relationship is super-linear), and be far more productive and innovative.

Over the weekend I watched this interview discussion between Elon Musk and Marques Brownlee. If it doesn’t show up below, you can find the video here.

Elon figures that if Tesla works really hard they could probably come out with a USD 25,000 car in about three years. The key to that affordability is twofold: (1) design & technology improvements and (2) scale.
So part of the answer is just time. As design and engineering iterations continue to take place, the components will become better and cheaper, just as they have for things like cell phones. Elon estimates that we’re in the 30th iteration of the cell phone today.
But the second factor is simply volume. And that got me thinking about housing production and the similar importance of scale and density. We do a lot to limit volume, despite saying we want more affordable housing.
