 \subsection{Explainability}
 
+Recent advances in artificial intelligence can mostly be attributed to an
+ever-increasing model complexity, made possible by massive deep neural networks
+(DNNs) and other similarly complex architectures. Due to their size models are
+treated as black-boxes with no apparent way to know how a particular prediction
+came to be. This lack of explainability disallows humans to trust artificial
+intelligence systems especially in critical areas such as medicine.
