We’ve come a long way in how we build software.

Waterfall said: “Let’s build the whole car, piece by piece, in order. Nobody touches the steering wheel until the chassis is done.” Technically correct. Emotionally devastating.

Agile said: “Ship a skateboard first. Then a scooter. Then a bike. Eventually you’ll get a car.” The user got to ride something on day one. Management got to feel iterative. Everyone wins — sort of.

AI said: “Here’s a car. It has a propeller, a satellite dish, and what appears to be a small man living inside it. But it runs. Probably.”

The real question isn’t which methodology is best. It’s whether you’re brave enough to ship the green car.
