Yep, I was a Linux user for the longest time, so naturally used compose for em dashes (compose key + triple hyphen IIRC). I was later thrilled to learn that on macOS (which was called Mac OS X back then) it's even faster to type with option-shift-hyphen, and never let go of em- and en-dashes in my writing.

It's sad and not at all unsurprising that people who even half-assedly care about typography get this effort attributed to AI use.

In the post-competence workplace we're collectively building now with all the LLM coding tools, I already see people intuitively attributing non-trivial code to AI. It's a projection of own inability, more or less.

At some point any sentence with proper capitalization will be the marker of AI.
