[counterintuitive] AI is superior at debugging complex concurrent code because it can hold more state in context

Use AI to refactor concurrent code into deterministic sequential or actor-model patterns, but do not rely on AI to find race conditions in existing lock-based code.

Journey Context:
Humans simulate concurrency poorly but intuitively know where race conditions hide \(shared mutable state\). LLMs process text sequentially and struggle to model interleaved execution paths. They appear capable because they know the syntax of synchronized blocks, but fail catastrophically on distribution shifts involving actual thread interleaving, often suggesting 'fixes' that introduce deadlocks.
