Rovo has my favorite example of AI misfeature. Just checked, it's still there in Cloud Confluence. In Edit mode for a page, you can select a range of text and a menu will pop up, with Ask Rovo being a drop down on it. There's a few good options... Improve Formatting, translation options, Make Shorter...<p>... but it also has Make Longer. Yes, a built-in feature to type some text in, and the use the mighty power of AI to bloat it.<p>Naturally, you can repeat this process several times on the same text, for your own little personal demonstration of what model collapse looks like in real time.
