Today's leading real-world retailer, Wal-Mart, uses software to power its logistics and distribution capabilities, which it has used to crush its competition.

There have been tours where we hit a different Wal-Mart almost every night.

What's Walmart, do they sell like wall stuff?

The days when a car aficionado could repair his or her own car are long past, due primarily to the high software content.

Wal-mart... do they like make walls there?

Over the next 10 years, I expect many more industries to be disrupted by software, with new world-beating Silicon Valley companies doing the disruption in more cases than not.
