This exact image (without the caption-header of course) was on one of the slides for one of the machine-learning related courses at my college, so I assume it's definitely out there somewhere and also was likely part of the training sets used by OpenAI. Also, the image in those slides has a different watermark at the bottom left, so it's fair to assume it's made its rounds.

Contradictory to this post, it was used as an example for a problem that machine learning can solve far better than any algorithms humans would come up with.
