Objectively good imho is as much a fallicy in the space of science and engineering as it is in art.

It takes the same artistic/creative skill to be a good engineer as it does an artist.

This is maybe a pedantic perspective, but i find it relevant.

Edit: objectively good for engineering is subjective expanation: you need requirements to define objectively good. I.e. sub optimal metrics to represent an entities value model. If you say hey, but engineers are structured/meticulous once they have the requirments.. i would say so are artists.
