The premise
AI can translate small COBOL paragraphs to Java or Python, but full-system translation requires equivalence harnesses, not vibes.
What AI does well here
- Explain a COBOL paragraph in plain English with assumed inputs.
- Translate small, pure functions with a test harness.
- Generate documentation of branching logic.
What AI cannot do
- Replace a 40-year-old system in a single conversion.
- Detect EBCDIC, packed-decimal, or business-rule edge cases reliably.
