Terence Tao discusses his experience with using modern coding agents to port his old Java applets to a modern supported language, and to create new apps, including a visualization tool for special relativity. The process was relatively painless, with the agent identifying and fixing bugs in the original code. Tao plans to use LLM agents to generate interactive visualizations as supplements for future papers. He notes that while LLMs can be useful tools, they should not be trusted for mission-critical tasks.
