alt Hacker NewsI'm sure someone's working on a way to tell the difference programmatically. Maybe a combo of tone, grammar, and some way of telling how fast it was typed using metadata (which may not exist). Even if there was a "probable AI" filter, that would be helpful because it would be a starting point to improve upon.
Lots of companies have products to that effect. They're all prone to false-positives, and are therefore worse than worthless.
This notion that AI-generated writing is something that's detectable is in and of itself flawed and really has no business in a community that alleges to have the technical aptitude necessary to know better.
