Author makes it very clear that the architecture rules are the same whether it's 70s or present day. The role of Software Architect didn't change much when it comes to core principles and ways of thinking.
The book doesn't provide many practical examples but instead relies on a self-reflection on the personal experience, encouraging to mentally revisit some of the projects that reader used to work on. It definitely revealed many insights and helped me to name, structure and defragment those architectural decisions that were eventually right but at the same time made purely intuitive. It also clearly showed those that were applied incorrectly or were just simply unsuitable.
Highly recommended not only to current architects who will find a lot of food for thought but also to aspiring software developers who want to start thinking about architectural questions in advance and drawing diagrams before the actual programming process.
