Context: LaTeX is a typesetting system. When compiling a document, a lot of really in-depth debugging information is printed, which can be borderline incomprehensible to anyone but LaTeX experts. It can also be a visual hindrance when looking for important information like errors.
Ironically the tom7 video about it using an AI to rewrite text to look prettier was the first time I learnt what badness and text layout in TeX actually meant.
