Agree, and the inverse problem is also prevalent, as we all know: someone without experience looks at a system, declares it to be shit while ignoring all the edge cases and design constraints that went into it, and insists they can do better by starting from scratch.
At a company I worked at, one of the VPs secured his son a "Senior Developer" role fresh out of a boot camp. His son was assigned to a high-visibility project that had been in development for several months and immediately started trashing it for using SQL instead of NoSQL, amongst many other reasons. He drew up some fancy diagrams and managed to convince people that the only way for the project to 'scale' was to do a rewrite from scratch with a new shiny tech stack. Several months later and they were still struggling to deliver a "Hello World".
