Bob Martin gives a talk about clean architecture, discussing how frameworks like Rails (and by extension Laravel) should not dominate application design. He emphasizes that web frameworks are just I/O devices and should be treated as plugins to the core business logic. He discusses the importance of proper architecture that allows deferring major decisions, separates business logic from delivery mechanisms, and enables easy testing. He also touches on the growing responsibility of software developers in society and the need for self-regulation through practices like TDD.
