> MASSIVE EM DASH Tangent: the thing I find most annoying about ChatGPT's use of em-dashes is that it never even uses them for the one thing they're best suited for. ChatGPT's em-dashes could almost always be replaced with a colon or a comma. But the true non-redundant-syntax use of em-dashes in English prose, is in the embedding into a sentence of self-interruptive 'joiner' sub-sentences that can themselves bear pun…
> These things are spoken entirely differently than — and on the page, they read entirely differently to — regular parenthetical-bearing sentences. > No, seriously, compare/contrast: "these things are spoken entirely differently than (and on the page, they read entirely differently to) regular parenthetical-bearing sentences." Those are spoken the same way, they read the same way, and they mean the same thing.
Aside: it's probably just style (maybe some style guides call for the way you did it), but using em-dashes for this purpose with whitespace on each side of them looks/feels wrong to me. Anyone know if that's regional or something?
