Let's create a slice category constructed like this:

f1: iPhone1 -> iPhone
f2: iPhone 2 -> iPhone
...
fn: iPhone n -> iPhone

g1: f1 -> f2
g2: f2-> f3
...

Then, there should be a pullback category A, so that

f1': A -> iPhone1
f2': A -> iPhone2
...
fn': A -> iPhone n

What would it be?

BASSANIO

Gratiano speaks an infinite deal of nothing, more
than any man in all Venice. His reasons are as two
grains of wheat hid in two bushels of chaff: you
shall seek all day ere you find them, and when you
have them, they are not worth the search.


--- W. Shakespeare. The Merchant of Venice.
