The promise and the practice

Here is this book's position, stated once so every later chapter can build on it. The 70% is real and it is wonderful: figure 1.2 shows what one prompt genuinely buys you on day one, and it is more than most 2020 startups had after a month. The 30% is also real, it does not disappear because the marketing does not mention it, and it is learnable without learning to code. Chapters 4 to 12 are that 30%, translated for someone who will never open the files: prompting that does not burn money, a method for the error loop, a backend you can explain, payments, a security pass, a budget, an exit route, and a weekly routine. This book is about the whole 100.
