Isaac Askew and Jeffrey Sherman explore the complexities of iterative development versus complete rewrites in software engineering. They discuss the challenges of legacy frameworks, the importance of intentionality in adopting new technologies, and the necessity of communication among teams. The discussion also highlights the Strangler Fig pattern as a viable strategy for transitioning to new frameworks while maintaining existing systems. Ultimately, they conclude that iterative development does not prevent the adoption of new frameworks and can lead to better outcomes than a Big Bang rewrite.
