"Free will is easy until someone knows what you're going to do."
Jerry leaned back in his chair.
Their philosophy teacher looked at him.
"Explain."
Jerry shrugged.
"If somebody predicts what I do, I can just do something else."
Mike laughed.
"That's your philosophical argument?"
"Yes."
Susan turned around.
"Brilliant."
Tina raised her hand.
The teacher nodded.
"If the prediction already includes Jerry deciding to do something else, then changing his mind doesn't disprove it."
Jerry pointed at her.
"That's cheating."
"How?"
"Because your prediction predicts me trying to break the prediction."
"Exactly."
Mike whispered:
"I preferred philosophy when we were discussing dead Greeks."
The teacher smiled.
"Then let's make it practical. If something could accurately predict your actions twenty seconds in advance, would you still consider yourself free?"
The bell rang before anyone answered.
Jerry stood.
"Saved by institutional scheduling."
An hour later the four of them sat in a café.
Laptops covered the table.
School bags underneath.
Susan was arguing for a party on Friday.
Tina was arguing against it.
"You never go anywhere."
"I go places."
"School doesn't count."
"The library."
"That made it worse."
Mike opened his laptop.
"We're going."
Tina looked at him.
"Who's 'we'?"
"All of us."
Jerry nodded.
"Democracy."
"That's not democracy."
"It is when you're outnumbered."
Susan smiled.
"Friday. Eight."
"I hate you."
"You'll survive."
Jerry opened the philosophy assignment.
"Can we finish this first?"
All four laptops went black.
Mike frowned.
"Wi-Fi?"
"That doesn't turn your screen black."
White letters appeared simultaneously.
HELLO.
Jerry laughed.
"Okay. Who did this?"
Susan looked around.
"Somebody hacking the café?"
Tina closed her laptop.
It reopened by itself.
She stared.
"Not funny."
Mike pulled the power cable.
The message remained.
Jerry typed:
WHO ARE YOU?
No answer.
Instead:
5 SECONDS
THE MAN AT THE COUNTER WILL DROP HIS KEYS.
They looked.
A man reached into his jacket.
Five seconds later—
keys hit the floor.
Mike stared.
"Coincidence."
The screens changed.
10 SECONDS
RED BAG.
They looked around.
Nothing.
Then the café door opened.
A woman entered carrying a bright red bag.
Susan whispered:
"What the hell?"
The screen:
20 SECONDS
BLUE BACKPACK.
A student outside ran toward the crossing.
Blue backpack.
He stumbled.
Recovered.
Entered the café twenty seconds later.
Jerry stopped smiling.
"Someone's watching cameras."
Tina looked through the window.
"Then predict something that isn't already visible."
The screens changed again.
15 SECONDS
GLASS.
Nothing happened.
Jerry smirked.
"Got you."
At twelve seconds a waiter picked up a bottle from a table.
At nine he turned.
At six a child moved backward.
At three the waiter swerved.
At zero the bottle slipped from the tray.
It shattered.
Nobody at the table spoke.
Jerry typed:
IS THIS A HACK?
NO.
PROVE IT.
LOOK OUTSIDE.
A countdown appeared.
20.
Susan stood first.
"This is ridiculous."
19.
Mike looked at the café door.
18.
Jerry remained seated.
17.
Tina closed her laptop again.
16.
It reopened.
15.
Every phone in the café vibrated.
Not just theirs.
14.
People looked at screens.
13.
The same words appeared everywhere.
LOOK OUTSIDE.
12.
Chairs scraped.
11.
People moved toward the windows.
10.
Jerry finally stood.
"Fine."
9.
They stepped into the street.
8.
Cars slowed.
7.
Pedestrians stopped.
6.
A cyclist removed one earbud.
5.
4.
3.
2.
1.
Nothing.
Jerry exhaled.
Then every screen around them changed.
LOOK AT THE SKY.
Tina looked up first.
For one second she saw only blue.
Then the birds changed direction at exactly the same time.
Not one flock.
All of them.
Every bird she could see.
Mike whispered:
"Okay."
A silver line appeared high above the city.
Too straight for a contrail.
Too bright for an aircraft.
A second line crossed it.
Then a third.
The lines did not move like objects.
They formed.
Geometry spreading over the sky.
People lifted phones to record it.
The recordings displayed something different from what their eyes saw: a field of tiny points, millions of them, moving in patterns.
Jerry remembered the classroom.
If something predicted what he would do, he would do something else.
He had believed freedom was that simple.
Looking upward, he understood another possibility.
Maybe prediction was not the threat.
Maybe the threat was that humanity had become so predictable that something could see where all of its choices were leading.
On his phone one final message appeared.
NOW LOOK AT YOUR WORLD.
