Your company's software enhances the process somehow, making it easier or faster or cheaper. Your company's software did not unlock the technology of road building.

There were roads built before your company's software and I'm sure if your company disappeared that ultimately roads would get built with or without their software.

It would be interesting to look at all the technological advances of the last 60 years and break them down into categories based on what happens if they went away though (category A: the field just goes back to 1950s and we more or less get by vs Category B: society utterly collapses).
