The "contrived textbook example from 20 years ago" still has a very real impact today. In my experience there are still lots of development teams that are instructed to develop in a "Clean code" style in the flavour of Uncle Bob. It's especially true in the .net development space, and is almost a cultural problem within .net.

As a former .net developer that was often pushed into "clean code", my big takeaway from the video was that actually, not using "clean code" techniques, such as polymorphism made the code so much more readable and easier to grok that the optimisation that followed was completely natural.
