The blogpost makes some good points, but it's extremely selective in choosing examples to support the author's thesis. Mainly in that it ignores many examples of orthographic ligatures that don't fit the author's narrative. A (further deep-)linked blogpost on ligatures in general states: > Ligatures were invented to solve a practical typesetting problem. In the days of metal fonts, certain characters had features that physically collided with other characters. To fix this, font foundries cast ligatures fonts [0] But that's not true. That is why ligatures are used by many foundries more recently, but it's not why they were invented, and it doesn't cover all traditional uses of ligatures. German and French orthography in particular contain a lot of examples that are closer to programming operators in use than the author's "fi" example.
