Thermal fuse in your printer can prevent fire hazard.

Hello, Thermal fuse in your printer can prevent fire hazard.
Somehow I do not see these mentioned / tested by paid influencers that I would not give anything to test due to their stupidity in the first place.

There are fuses available up to 300C so should be perfect even if you use engineering materials like Nylon.
Do not mistaken these with bi-metalic ones, these ones are single use, guaranteed to blow used in motor winding, transformers, etc.

I do not see them incorporated win hotend part of extruders, hmm?

Decent software can detect and shut down over temperature problems when they occur. I have a thermal fuse on my Voron heated bed but that is simply providing double protection along with the Klipper software.

Software protection can fail, this video demonstrates this:

Some of the cheap machines don't even have thermal runaway protection in the firmare, in fact many of the early Creality machines had memory chips so tiny they allegedly remove the protection code to add more features.
I'm quite happy with mine, Klipper has many safety features built in and I never print without monitoring the machine.

Software protection can fail,

I don’t really know what sort of thermal protection there are in any of my printers, and I seldom monitor the printers when running, sometimes my print runs have taken 4 days nonstop to complete.. I’ve never had any problems or issues with high temperatures..

The most expensive printer I bought was €400 and worth every penny, Chinese or not..
