I re-watch it every so often to help prevent my thinking from falling into a rut. When developing software as a career, it's so easy to just fall into a pattern where you use the same tools and techniques over and over again.
Watching this talk this talk inspires me to investigate alternate approaches to developing and delivering software. It's easy to think of software development as something that always need to involve code, and nothing but code. But watching this talk inspires me to go and try things like Node Red and Unreal Blueprints. In both cases, code is usually still involved, but they both offer a visual way of connecting components. I find it helpful to be able to visualize software this way so I can immediate understand how data flows through the application.
