The hosts once again discuss the recurring theme of AI’s impact on development workflows.  They discuss various topics, including: 

• Increased PR volume from AI-assisted coding and whether traditional pull request reviews are still necessary. 
• Should AI be used earlier for pre-PR review and stronger CI guardrails for performance and security. 
• What is the role of automated testing, and are they even more important as code generation accelerates?
