You don't need to listen to this talk if you use React for small applications, demos, or proof of concepts, as it will only complicate your life.
However, this talk is for you if you are struggling to manage small applications that have grown too big or are unsure of the best architecture for your single-page application. Learn how to create a three-tier UI architecture by applying the correct design principles and patterns to build clean, maintainable, testable, and scalable applications.

ps: we will not discuss folder structure during this talk :)
