I'm thinking about adopting the clean architecture. the main thing in this architecture as I understand it is the dependency flow from top to bottom. so the first thing that I asked myself is what would be the cost to change the bottom layers(i.e Entities)? this layer will have lots of dependencies and by changing it I will have to change all the layers up to the top. Am I right or I'm missing something?
