Armin Ronacher discusses his experience with AI-generated code, revealing that over 90% of the code for a recent project was written by AI tools. He emphasizes the importance of maintaining responsibility for the code, careful oversight, and understanding system architecture, despite the efficiencies gained through AI assistance. Ronacher believes that while AI can significantly enhance coding efficiency, it does not replace the need for skilled engineering judgment.

Robinhood CEO Vlad Tenev revealed that nearly all of the company's new code is written by AI, with around 50% of it being AI-generated, a figure notably higher than estimates from Microsoft and Google. He emphasized the challenges in distinguishing between human-written and AI-generated code, attributing the significant adoption of AI tools like GitHub Copilot among engineers to improved efficiency and cost stabilization within the company.
