When the functionality of a product or service overshoots what customers can use, it changes the way companies have to compete. When the product isn't yet good enough, the way you compete is by making better products. In order to make better products, the architecture of the product has to be interdependent and proprietary in character.

By the time it becomes obvious that a technology will have truly disruptive impact, it is often too late to take action. This is one reason why we are such advocates of using theory to try to analyze industry change. Conclusive evidence that proves that a company needs to take action almost never exists. In fact, the data can fool management, lulling them into a false sense of security.

Innovation simply isn't as unpredictable as many people think. There isn't a cookbook yet, but we're getting there.

Intimate, loving, and enduring relationships with our family and close friends will be among the sources of the deepest joy in our lives.

Efficiency innovations provide return on investment in 12-18 months. Empowering innovations take 5-10 years to yield a return. We have ample capital - oceans of capital - that is being reinvested into efficiency innovation.

What you need is a fundamental humility - the belief that you can learn from anyone.

Disruptive innovations create jobs, efficiency innovations destroy them.
