This is a lot of words to double-down on a false dichotomy: that you either copy paste code from the internet or you write it painstakingly from scratch. IMHO

This is a lot of words to double-down on a false dichotomy: that you either copy paste code from the internet or you write it painstakingly from scratch. IMHO you don't pass junior level without the ability to efficiently google for solutions at the right zoom level. This starts with understanding what you are reading and the best way to use that information, whether it be integrating a library, integrating a small snippet, disregarding as inapplicable, or mixing and matching ideas from multiple sources. The very specific conclusion that the author jumps to lacks nuance. It's hard to say based on this whether the programmers are as bad as the picture he paints, or if it's primarily a management failure.
