Sadly the author doesn't understand what iterating quickly means. It's not a means of achieving greater performance in a known area, but a means of finding something that works in an unknown space.

So the completely opposite argumentation would've worked. For the last 10+ years we spent iterating over several startups to find how to use this new technology of mobile and internet, and now that we have found most reasonable usecases we can slow down and optimize them.

On the other hand there are always areas we don't know much about, like in the areas of shared knowledge, in the niches. There of course quick iteration continues to be the way to go.
