Watching Brandolini is fun. He always have fun slides to look at and a humorous way to express his ideas. This talk is no exception. There are two things I would like to highlight:
Brandolini thinks using Lo-Fi tools (like sticky notes, pen and paper) is superior to digital alternatives because when using them you focus is modelling instead of tidying the diagram. He says: "Digital tools are changing your brain priorities. I enter a session to model, and I find myself aligning rectangles and making arrows clear."
Following the domain expert wherever they go is not necessarily a good idea. In many cases, the domain expert will push for a quick fix in the system instead of aligning the code base with the business and that will not be beneficial in the long run.
