The dark bar at the bottom is a human.
Below: the paragraph from the book that builds this idea, then the diagram itself (Figure 4.1), and a recap. About a minute of reading.
Figure 4.1 is the chapter in one picture. It is built entirely from Vapi's own worked timeline, drawn to scale, with three configurations of the same assistant and the human benchmark on the same axis so you can see the size of the gap rather than read about it.
Recap
