Expanding: Think of it this way: A typical sprint in current best practices is 1-2 weeks. Having to scrap a module and start over loses you a lot of time and money. A typical "AI sprint " is << 20 minutes. Several passes of failing a module and rewriting the spec is still only a few hours.

A typical rant is "You claim only the output is what counts; but what about the human warmth?". Well, this is IT. If you can thoroughly prove that the inputs and outputs are identical to spec you have done the thing.

Harder than it sounds: CDNs and suss libraries no one told you about, abysmal security, half baked features? Uh.... yeah that happens. But if the blast radius is small, it's fixable and survivable. Hopefully.

Famous last words.
