Unpopular opinion, Robert C Martin has caused more harm than good. People take his ideas and blindly follow them no matter the cost. I’m looking at you clean architecture.
To me the difference was in recognizing that the architecture advice is implicit - its not actually written down in the code, rather the code exemplifies it - and the business domain is explicitly modeled. When developers name everything "use case" and "interactor" and go crazy with packages and folder structures with architectural names it's a recipe for terribleness.
