n this talk, we'll explore how collaboration with AI can transform the way we develop and optimize applications. We'll start by comparing real code examples to analyze which is more efficient, using benchmarking tools like BenchmarkDotNet to validate our assumptions with concrete data. Then, we'll take it a step further: with the help of AI agents, we'll create and optimize a concurrent processing system (JobSystem), integrating their suggestions to enhance performance. We'll discover how AI can not only propose code improvements but also help build detailed benchmarks more quickly.
