Vectors will scale to any pixel density, but they look irritatingly fuzzy at the lower pixel densities you commonly see in large widescreen monitors.
Obviously it's not an apples-to-apples comparison, but decades ago bitmapped fonts could give you crisp text on any monitor, and in 2022 I'm using a popular, >$1300, very favorably reviewed monitor, and the text is ever-so-slightly fuzzy. It's plugged into my Macbook Pro right now, and the difference in how well the text renders on the two displays is plain.
I guess as soon as Apple started making laptops with 300dpi screens, it became okay to render fuzzy text on any screen that wasn't 300dpi.
