Yup, it's real. How did it get into production with
- a flattened back tire with central hub very off-center,
- right pedal on the left side, and very far below the cyclist's leg,
- chain routing defying common sense,
- and a disjointed left glass?
At least the socks seem to be classic low-res stitch art likely by humans...
Some people do. There are endless little language tricks that some people will catch and others won't. Similarly there are endless visual tricks that some people will catch and others won't.
If you're looking for a trick, it'll be easier to spot. Any image posted to the "Fuck AI" community is going to have people looking at it. But put this online with 20 other socks for sale or at the checkout of a store and no one (realistically almost no one) is going to catch it.
