The Download: YouTube's deadly crafts, and DeepMind's new chatbot

Ann Reardon is probably the last person whose content you'd expect to be banned from YouTube. A former Australian youth worker and a mother of three, she's been teaching millions of loyal subscribers how to bake since 2011. But the removal email was referring to a video that was not Reardon's typical sugar-paste fare. Since 2018, Reardon has used her platform to warn viewers about dangerous new "craft hacks" that are sweeping YouTube, tackling unsafe activities such as poaching eggs in a microwave, bleaching strawberries, and using a Coke can and a flame to pop popcorn. The most serious is "fractal wood burning", which involves shooting a high-voltage electrical current across dampened wood to burn a twisting, turning branch-like pattern in its surface. The practice has killed at least 33 people since 2016.
