There’s em dashes in that 1978 article.

The typed original [1] has double hyphens that have been converted to dashes. His typewriter (Hermes Ambassador) was fixed pitch.

It's not just em dashes, it's 1: typewriter em dashes aka `--` and 2: usage of them in pairs, like parenthesis, that is completely different from how LLMs use them.
