As much as I'd like to know whether a text was written by a human or not, I'm saddened by the fact that some of these writing patterns have been poisoned by these tools. I enjoy, use, and find many of them to be an elegant way to get a point across. And I refuse to give up the em dash! So if that flags any of my writing—so be it.
Believe me I've had to adjust my writing a lot to avoid these tells, even academics I know are second guessing everything they've ever been taught. It's quite sad but I think it will result in a more personable internet as people try to distinguish themselves from the bots.
I applaud your optimism, but I think the internet is a lost cause. Humans who value communicating with other humans will need to retreat into niche communities with zero tolerance for bots. Filtering out bot content will likely continue to be impossible, but we'll eventually settle on a good way to determine if someone is human. I just hope we won't have to give up our privacy and anonymity for it.
