Everything exists in four dimensions (space + time). If a thing “looks good” in three of them but falls apart in the fourth (e.g., it works right at this moment but its continued existence is an impossibility or a hassle—be it physical artifact made from subpar material, unmaintainable tangle of excess code, etc.), then that thing does not look good. Getting a hang of what things look like in the fourth requires skill and wisdom that probably partly comes from having traveled it yourself.
