Scientists invented a fake disease. AI told people it was real Bixonimania doesn’t exist except in a clutch of obviously bogus academic papers. So why did AI chatbots warn people about this fictional illness?

It's going to take a while to sort out the AI slop and hallucinations.

As a Minnesotan, I have been deeply affected by the shootings of Melissa and Mark Hortman, Renee Macklin Good, and Alex Pretti. I wrote this song for them, and workshopped it with students at the Svoboda Center for Civic Engagement at St. Olaf College.

Reminder: All it would take to end the murder of American citizens by an untrained government goon squad is 16 Republicans in Congress voting with Dems to defund ICE (or 23 to impeach and remove Trump — 3 in House & 20 in Senate). That’s it. 23 Americans can vote for the public and end all of this.
