We have spent six lessons on how these tools work and where they break. Let us end by being
clear about what stays yours.
It cannot know what you want. It only knows what you typed. The picture in your head is
not in the context window. It never is.
It cannot decide what is worth building. It will happily build a feature nobody needs,
beautifully, in four seconds. It has no opinion about whether the work is worth doing.
It cannot be responsible. If the code you ship charges a customer twice, that is your
name on it. “The AI wrote it” has never once helped anybody in that conversation.
It cannot check things it cannot see. It does not know your users, your production
server, or that one strange rule your business follows for historical reasons.
It cannot hold your standards. It will match the quality of whatever it is shown. Point
it at a messy project and it writes messy code that fits right in.
Why this is good news
Read that list again. Deciding what to build. Saying clearly what you mean. Judging whether
the result is good. Taking responsibility.
That was always the actual job. The typing was never the job. Typing was just the part that
took the most time, so it felt like the job.
These tools remove the typing. They do not remove the work, and they do not remove you.
They move you from writing every line to deciding what every line should do. That is a
promotion, and like every promotion, it needs skills you have not practised yet.
Those skills are the rest of this course.
Where you are going
- Module 2 teaches you to say what you want, precisely enough to get it.
- Module 3 gives the model hands, and you the controls.
- Module 4 builds a real application, one small piece at a time.
- Module 5 teaches you to check work you did not write.
- Module 6 makes the tool behave like it knows your project.
- Module 7 puts your project on the internet, where other people can use it.
Before Module 2
- Write down one thing you actually want to build. Two sentences, no more.
- Show those two sentences to a friend. Ask them to describe what they think you mean.
Where they guessed differently from what you intended, you found an unclear instruction. - Keep that piece of paper. You will use it in Module 2.
