In this talk, we will discuss evidence that maximal chaos occurs for a generic probe quark-like degree of freedom, in a strongly coupled large-N theory. We will demonstrate this by extracting an effective Schwarzian action that describes the low energy physics of a long, open string embedded in AdS. We will argue that this maximal chaos is an inherent feature of the string worldsheet, and further present an example where an intrinsic D- brane horizon, away from extremality, yields a similar result. We will conclude with open questions and possible future investigations.
