While a cute joke, I think the "server" and "data-center" images don't really work at all in the analogy and in the end detract from the overall message.

I do wish this image somehow incorporated an analogy for (graphic) design, which is a related domain that people seem to muddle together with UI and UX. I'd find a simple, understandable analogy that distinguishes the three useful. The only thing I can think of is the shape/color/texture of the cereal and/or the ornamentation of the spoon and bowl, but those both feel like a trivialization of design (i.e., it's more than picking shapes and colors).

While colours don't always play a role, they often do. Shapes definitely play a major role in graphic design. I think it's all about the shapes and proportions.

Eating with a spoon that's bigger than your mouth would be poor design for many humans. Design plays a really big role in usability.
