Let’s take a hike on the coast from San Francisco to Los Angeles to visit our friends in Newport Beach. I’ll whip out my map and draw our route down the coast:The line is about 400 miles long; we can walk 4 miles per hour for 10 hours per day, so we’ll be there in 10 days. We call our friends and book dinner for next Sunday night, when we will roll in triumphantly at 6 p.m. They can’t wait! We get up early the next day giddy with the excitement of fresh adventure.  We strap on our backpacks, whip out our map, and plan our first day. We look at the map. Uh oh:

  • The software is completely intangible; it doesn’t require big machines to dig holes or move heavy objects. It doesn’t require complex permitting or regulatory approval. And a single talented programmer can create a very large amount of code very quickly to the extent that a very capable single developer can actually create an entire shippable product him or herself. Contrast this with say, a single worker attempting to build an entire skyscraper alone. The virtual aspect of software completely changes the rate at which products can be constructed and the resources required.
