JOBU TUPAKI. A little change. A lot of possibility.

A playground for possible worlds

Change one thing.
Explore what
happens next.

A different decision. A tiny twist. An entirely new chain of events. Follow your curiosity and see where the dominoes fall.

Your universe starts below

01 / Open a possibility

No idea is too small. Or too strange.

Change one thing in the real world, or invent your own.

Choose the mood

Plausible consequences, competing possibilities, clear assumptions.

Need a spark?

02 / A glimpse of what’s possible

Sample thought experiment

What if a city made all its buses free?

The fare disappears.
The ripple effects don’t.

Imagine stepping onto a bus without reaching for your wallet. A small everyday friction vanishes. Where does that lead?

The first dominoes

  1. 01

    A trip becomes easier to say yes to.

    Some residents might make an extra trip to a job interview, a class, or a friend. The route and timetable still decide whether the ride is useful.

  2. 02

    The question moves from fare to frequency.

    If more people ride, a packed bus becomes a new problem. More frequent service could matter more than the price of a ticket.

  3. 03

    Someone still pays for the journey.

    The city needs another way to cover the lost fares. That choice might shape which residents benefit, and what other spending changes.

What this scenario assumes
  • This is an illustrative fictional city, not a report on an existing policy.
  • The city has an operating bus network and must replace its fare revenue.
  • Different funding and service choices could produce different outcomes.

That’s one possible world. What would you change?

Try your own thought experiment

Possible worlds, not predictions. These generated thought experiments may contain mistakes and don’t check live news. Check factual claims before relying on them.

Curiosity is the whole point

Big ideas.
Small beginnings.

Start with one change. Follow the consequences. Then challenge the answer.

Go grounded for a thoughtful chain of possibilities, playful for a little wit, or completely unhinged when reality has had quite enough of your attention.

You don’t have to agree with the world you find. Sometimes the interesting part is asking why.
