The Hitchhiker's Guide to the Galaxy (series)

What it’s about

Arthur Dent’s house is about to be demolished for a bypass, and then so is the Earth, for a hyperspace bypass. Rescued by his friend Ford Prefect, who turns out to be a researcher for the Hitchhiker’s Guide to the Galaxy, Arthur is dragged across the universe. Along the way we learn that a supercomputer called Deep Thought spent seven and a half million years calculating the answer to life, the universe and everything, and the answer is 42. The rest of the series gets stranger from there.

What I learned

A perfect answer to a vague question is useless. Deep Thought’s answer is correct. Nobody knows what the question was. That’s a joke about philosophy, and a very good description of working with AI.

Don’t Panic. Printed in large, friendly letters on the cover of the Guide. Calm is a skill, and it’s the one that matters most when everything is on fire.

Absurdity is a coping mechanism. Adams takes huge, frightening ideas (the end of the world, the meaninglessness of it all) and makes them funny without making them small.

What I applied

This is reflection, but two ideas show up in my working life all the time.

Deep Thought is the original parable for prompting. The quality of what an AI gives you depends on how well you’ve framed the question and the context around it. Much of my current work with coding agents is really question-writing: clear briefs, explicit constraints and a definition of done. A failing test, for example, is a very precise question (TDD as a Feedback Loop).

Don’t Panic is incident response. When production breaks, the first job is to slow down: stabilise, communicate, then investigate. Shedding non-essential work so the core keeps going is the system-level version of not panicking (Regress, Don’t Grind: Graceful Degradation).
