We don't know if it made "the problem" worse. It certainly made it worse for the guy getting poisoned. But it's possible that for each person getting poisoned, there's a couple not getting poisoned because the app correctly ID'd a mushroom. Or a hundred people who have their intellectual curiosity satisfied. I recently used Google Lens to ID (with like 75% confidence) a mushroom I had zero intention of eating either way. Mushroom identifying books have all of the same issues. I guess one could make an argument that it's unconscionable to publish those, too.
