...and, let's face it, the relative complexity of a skyscraper compared to a computer software program, given equal cost, is very, very low. A skyscraper costs hundreds of millions to construct. An equally costly software project would be something like the entire lifespan of the .NET Framework including the CLR, Standard Library, C#, VB.NET, Silverlight, all of the "Enterprise" features, etc.

Also, software isn't really construction. It's built by the people who design it, for the most part. Imagine a skyscraper (or car, bridge, etc) built entirely by engineers. Yikes.
