That wasn't a response to you. It was a response to the remark that the
Trisquel 8 alpha is "stable". It also wasn't in "anger"; I don't know why you
interpreted it that way.

Unless "damage" just refers to normal wear and tear from using the hardware
normally, that's not possible no matter what the software does, especially
not unintentionally (the only possible way I can think of is for the software
to disable all cooling systems and then run infinite loops hoping to heat up
the processor, but any well-designed processor that can heat itself up will
shut itself off before it gets too hot).
The only risk that comes with using software that's not ready yet is data
loss. At least, assuming it's on hardware that's competently designed.
