Any industry that wants to be sustainable must think long term. In the timber industry they need to worry about the future availability of trees, for fisheries they need to think about fish - you get the point. If any industry does not pay attention to replenishing the font of its raw materials, this is an industry that is setting itself up for major problems. Don't replant trees or don't allow fisheries time to replenish themselves and things are going to end badly.
Seen through this lens, the software industry is a slash-and-burn operation.
