Yes. These are extremely rare. Some models, like iirc a galaxy note and MacBook Pro have been singled out. The surface and airflow also matter. A laptop kept on a desk spends very little time charging at a time and any heat is dissipated efficiently. All devices are designed with the best thermal performance they can have.
There was actually a house fire a while ago not too far from where I live that forensics said was started by a device in a charger at night. For some units and some uses, they still fail.
Anyway. I think the better safe than sorry is warranted.
Speaking is very different. And yes, there's very much a point to the attempt. I'm saying it doesn't work in text, especially not in this vague form that most people won't ever know about.
Hot air/gas, hot water/liquid, and a hot solid behaved very differently. The numbers depend a lot on what's being measured. There's also a big variable of time.
There is plenty of genocide, war, and all that. It's just done at a sustainable pace and mostly in places that don't look like US soil. Hitler rushed and got a reaction. This time it's going to be worse.
May work well for show, but remember that fdm prints are never food safe.
