Right so the author has taken the most extreme level of weirdness and tried to use it as an example of normal image generator output. Thats quite dishonest.
Totally anecdotal, just tonight i saw a video my child was watching with generated images. At first i thought, I've seen that face in generated images, i think, then we looked a little closer, and noticed obvious mistakes (extra or weird fingers, weird body positions, cross eyes where you wouldn't expect them).
Of course it's the first time I've spotted it in the wild where it wasn't explicitly marked as generated content, so maybe i've missed a bunch.
