Life After Business Objects - Confessions of an OOP Veteran

Explore the transition from object-oriented programming to functional programming in this conference talk by Vagif Abilov, a senior consultant with over 30 years of programming experience. Delve into the advantages of functional programming for projects with short deadlines and continuous deployment. Learn about modeling data structures in F#, the limitations of OOP, and the benefits of algebraic data types. Examine concepts like Amdahl's law, domain modeling, and the actor model. Discover how functional programming impacts feature development cycles and the main advantages gained from adopting this paradigm. Gain insights from industry experts like Joe Armstrong, Scott Wlaschin, and Alan Kay on topics ranging from business objects to the nature of object-oriented programming.
