The basic idea is that we continually discover new chemistries that change the slope of the curve. And all of these chemistries seem to allow for linear-like growth for that particular chemistry. It's also pretty safe to say that there have been several long stretches of time since the early 1900s where it would appear that there was little or no improvement at all since the "jumps" that come along with the discovery of new chemistries happens rather suddenly.
