Was my first thought too. He's judging "workload" by how much time it takes up front to write a program, which may be an important metric for "move fast, break things" social/mobile/local/web apps and the like. But he doesn't mention error rates, maintenance costs, LoC, or any other metric that mission/safety/life critical systems prioritize.

The world view underlying this post is one of the reasons for shoddy software and all the breaches, data thefts, etc. that have successfully exploited systems flaws in recent years.
