I much agree with that the complexity is the limiting factor and you probably will need specialized people to model and design not only what the computer does but how the humans and computer co-operate. When you're programming you are not only programming the computer but also the people who use your application(s). Describing and designing and validating asynchronous processes is especially complicated.
