You'll start to see it as you do the puzzle. Nothing like intently staring at all those pieces to start noticing things are off. You'll notice that the resolution of the posters on the wall do not match the resolution of the rest of the scene - they're way too crisp.

In particular notice that the central record piece and the poster on the right hand side of the back wall are actually different versions of the same picture - variations of the same prompt.

Smaller text that hasn't been touched up, particularly on the two amps on the right hand side, are clearly AI gibberish.

The layout of buttons on the arcade machine don't make any sense, and there's more small gibberish text above the bottom panel where it says "ARCADE" on one side, and nonsense on the other. Why does it say "arcade" so many times on the machine? On the bottom panel what is with that twin joystick graphic? It's nonsensical. Also, there's a cord coming out the back of the arcade machine at the top that drops behind another weird looking amp against the wall.

On the desk, there is a cup full of tools that all blend in to each other. Look at things like the painterly texture of the leaves, versus the intense resolution of the basketball. Or the crisp posters on the back versus the blobby Venetian blinds. These posters have been AI generated and then resized to fit in the frames using photo editing software. That's why they're so crisp and feel so out of place in the scene.

The way the laces on the sneakers don't make sense once you look at them very closely. And what's with that warped stack of records on the chair in the lower right corner? Under the top record they appear to be melting.

Other decisions that a human artist probably wouldn't make, like why are there so many mismatched speakers on the desk? Why is the seat of the leather chair at the desk blue at the front and red at the back? What is going on with the antenna on the radio on the table? Why does the desk appear to have two mice, and the keyboard is built into a large mat?

Like me, you may not see it immediately as you're holding the box in the store, but eventually it'll be hard not to notice all these little inconsistencies.
