Interesting concept that attempts to solve a problem I wasn't aware of, AI's overuse of the Em-Dash. I'm curious about other markers to proof human authorship.

I'm not sure what stops AI from using this punctuation mark. They don't seem to scruple from plagarism or copyright violation.

It’s a rough time for those of us who have always used en- and em-dashes and who structure documents with bullet points.

I’m fortunate that writing comes easily and quickly, but these days probably most people who read my docs assume it’s AI. I can’t bring myself to abandon my beloved em-dashes though.

There are two possible outcomes:

1. Nobody will use the Amdash

2. AIs will pick it up and learn to use it

The end of the page needs an "Epilepsy ⹃ flickering lights" warning. Looks like the Loki Disney+ series intro, in cassette futurism style.

It's a font that morphes the text fragment "am-" into the curly dash using a ligature.

But that won't help for long. If the Amdash becomes popular, then AI will pick it up, because "am-" is just a text fragment and AI can learn to produce it.

Even worse if a future version of Unicode adopts the Amdash, then nothing will stop AI.

Or the opposite happens as one already said here: Nobody will use the Amdash.

That site is really hard to read. I was about to say it needed a designer, but it obviously had one. But the designer is either very bad or intentionally made the design very bad. I can't tell. I also can't tell if the author is serious or being satirical.

And that flashing image at the bottom could be dangerous for people with seizure disorders.

The styling of this reminds me of faces that cant and/or serif the hyphen. I checked a few, and in my very limited survey (Blado, Poliphilus, Trajanus and "related" faces for each that Monotype recommends) most type faces that style the hyphen do not change the appearance of the emdash at all from a horizontal line. The few counter-examples I found are italic faces (Balladeer by URW.)

If you're going to use a special font, why not use a font that completely scrambles the alphabet? That would actually be a challenge to AI

You can't solve the problem of malicious actors by asking them not to act maliciously.

> The am dash, with its pointed unusability by AI, serves as a subtle watermark of presence—a fingerprint smudged on the edge of a sentence.

They missed using the am-dash in this sentence and instead used an —

But this punctuation can only be used by common people when it’s included in other common fonts. Then it will also suffer from AI use over time and someone will invent yad-dash (yet another dash).
