No, but maybe the lesson is, people should chill a bit with criticism. It's easy to armchair-criticize anything, but the west has serious problems with infrastructure projects right now. Shooting down any attempt at doing something large-scale is counterproductive to the growth and survival of our society.

Besides, smartphones didn't come from nothing. Prototypes and similar things had been around since the 90s. And they are arguably a much easier problem than infrastructure.
