I’ve not heard of any lithium batteries for personal devices ever going off, producing flames in cabin areas.

I haven’t heard of any incidents, either. But I know these batteries can ignite. If they went off in the cabin, wouldn’t the fire still be very hard to put out?

You just need one dumb school kid who shorts out the USB port of his ChromeBook to overload the battery and ignite it.

Kids have been doing this in school.

I've seen the videos but not experienced a cabin fire myself yet. And it's really hard (near impossible) to extinguish them once they are lit. I don't know if it's just cheap Chinese manufacturing, or designed failure obsolescence, or conspiracy theory attacks that are driving the recent battery woes. But I can guarantee a lithium fire anywhere on the plane will ruin your day, but especially so where there are no humans to intervene.
