## Summary

The essay traces AI from IBM's Deep Blue, which beat the world chess champion in 1997, to today’s conversational systems like ChatGPT. Early systems relied on human‑written rules and deterministic evaluation criteria, a method that worked in closed domains such as chess but failed when applied to real‑world concepts like a "dog" with many exceptions. The author describes the classic frame problem, where an AI that checks every possible side effect becomes paralyzed.

The turning point came with representation learning and transformer models that ingest trillions of tokens from the internet, allowing the AI to discover statistical relationships between words without explicit rules. This probabilistic approach lets modern models handle ambiguous language and context, though the author notes that whether the frame problem is theoretically solved remains a subject of debate. The piece also speculates on how game developers might shift from hand‑coded rule sets to AI‑generated dialogue and content, while keeping core deterministic mechanics in code.

## Key points

- Deep Blue defeated the world chess champion in 1997 but could not sustain a conversation.
- Rule‑based expert systems used human‑written if‑then code and struggled with ambiguity and the frame problem.
- Transformers learn patterns from trillions of tokens, bypassing rule‑writing limits and enabling flexible language handling.

## Why it matters

Understanding the shift from rule‑based to data‑driven AI explains the capabilities of today’s generative models and guides future applications in areas like game development.
