It seems like every now and then we get someone doing dangerous science experiments in their backyards that threaten not only themselves but their neighbors as well. Brings to mind David Hahn, only worse since with AI the odds of it hallucinating a step and causing a serious problem is much higher.
I don't know, I could imagine that this changes when AI becomes more sensible than the average internet advice. Also I would like to see some evidence how dangerous the experiment with the AI inspired Fusor actually was. I recently read here "hiking in jeans" is dangerous.
Fusors are somewhat dangerous, they use extremely high voltage, in the thousands to hundred thousand volt range. x-rays become an issue above around 30,000 volts, but they are frequently made by high school students, and I'm not aware of any deaths.
