[counterintuitive] LLMs understand code the way humans do
Treat LLMs as statistical pattern matchers over code; always verify generated code with tests, type checkers, linters, and static analysis rather than trusting semantic understanding.
Journey Context:
It is easy to anthropomorphize code models because they produce syntactically valid programs, but their strength is interpolation over training examples, not grounded comprehension of execution semantics. They struggle with novel abstractions, corner cases, and specifications that differ from training distributions. The Codex paper and subsequent evaluations emphasize that generated code must be validated empirically. The correct workflow is LLM-generated draft \+ automated verification \+ human review for correctness, not blind trust in 'understanding.'
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
