I will give a leisurely introduction to double ∞-categories, provide a range of examples, and explain why these structures are useful. In particular, I will sketch how they play a key role in an abstract framework that systematically develops different generalizations of ∞-category theories (like equivariant and enriched versions). This was part of my PhD thesis.
