There are no shortcuts to the investment of time and care in friendship and human bonding, and it is fraudulent to pretend otherwise. When human loneliness becomes a source of income for others through devices, we'd better stop and think a bit about the place of human needs in the real world of technology.
Increasingly, I think UX doesn't live up to its original meaning of "user experience." Instead, much of the discipline today, as it's practiced in Big Tech firms, is better described by a new name.
The far more pernicious issue with pangrams, as a means for evaluating typefaces, is how poorly they portray what text actually looks like. Every language has a natural distribution of letters, from most to least common, English famously beginning with the E that accounts for one eighth of what we read, and ending with the Z that appears just once every 1,111 letters. Letter frequencies differ by language and by era — the J is ten times more popular in Dutch than English; biblical English unduly favors the H thanks to archaisms like thou and sayeth — but no language behaves the way pangrams do, with their forced distribution of exotics. Seven of the most visually awkward letters, the W, Y, V, K, X, J, and Z, are among the nine rarest in English, but pangrams force them into every sentence, guaranteeing that every paragraph will be riddled with holes. A typeface designer certainly can’t avoid accounting for these unruly characters, but there’s no reason that they should be disproportionately represented when evaluating how a typeface will perform.
