> Fun fact: wifi is not an acronym for anything, the inventors simply liked how it sounded.

Most certainly it's a reference to "Sci-Fi" or "Hi-Fi".

I always thought Wi-Fi meant wireless fidelity? (Or wireless fiction since in the end, everything is wired).

It doesn't, but the phrase was used in the early days.

t was made to sound like Hi-Fi, which stands for high fidelity, and Wireless, but "wireless fidelity" is a meaningless phrase and not what it was intended to directly mean.
