Apple Pay (launched around 12 years ago, and likely costing billions) is exactly the counter-example here. The 'code' was the easy part. The moat was the decade of hardware R&D and the leverage to force banks to adopt a new standard. An LLM might write the API wrapper in seconds, but it can't hallucinate a relationship with Visa and Mastercard. You literally cannot create a new Apple Pay in a week or even years, no matter how much you vibe code.

I'm sometimes baffled by what people think can pass as a product in a real sense.
