I see statements equivalent to these in the article:

- Cities are inefficient Rube-Goldberg contraptions

- Portions of city systems are too complex for one person to understand

- We see evidence of complex, unpredictable systems when things go wrong

- Cities have multiple complex systems that can and do produce unpredictable failures

- Methods inspired by scientific study may help us improve city life

I'd summarize it as: Here are some problems caused by complexity, and here are some (vague) ideas for how to fix them. From the article's content, I think there's an implied "yes" answer to the title.
