There are some things that are still weird to bring back. Like in comparison with pixel art: pixel art was a limitation but also a medium and the best art was created by masterfully utilizing it to its limits, but the PS1-style polygon z-fighting and weird texture warping were not seen as a medium, I can’t really think of a game that would utilize them for any artistic purpose, the most masterful use for them was to make them as invisible to end users as possible, and the whole art was in getting them to a minimum.
Introducing them purposefully and setting them center-stage feels weird, like building a new car out of rusty parts and making sure the seats properly smell of old farts. It is an aesthetic, for sure, but not an attractive one.
On Wikipedia it says it is a name of a Russian constructed language
"Kurvitz established the ZA/UM team to create the game, using the name "za um", a reference to the Zaum constructed language created by Russian avant-garde poets in the early 1900s. Its name can be read in Russian as a shortcut for the idiom взяться за ум (vzyat'sya za um), which is similar to the English idea of bootstrapping. The use of all-capitals and the slash symbol is to present the team as "something that definitely exists and weighs eight tonnes"."
