There is a growing belief that AI could reduce the relevance of tech debt due to easier code writing and cleanup. However, the reality is that AI has actually increased the cost of maintaining tech debt. Generative AI significantly enhances the performance of 'low-debt' coding compared to 'high-debt' coding, meaning companies with modern, high-quality codebases gain more advantages from AI tools, while those with legacy, complex codebases face greater challenges. The performance of tools like Cursor or Aider is

The speaker discusses their experience with formal specification projects in concurrent or distributed systems, which are challenging due to the complexities of concurrency. They acknowledge common reasons for the difficulty of concurrent programming, such as testing challenges and latent bugs, but argue against the idea that humans inherently struggle with concurrent reasoning. Instead, they suggest that people can effectively reason about concurrency when framed in relatable terms. The speaker points to "state space explosion" as a more fundamental issue, noting that concurrent systems can exist in vastly numerous states that
