Ok, I can see how my statement can be confusing. I wanted to say that on newly built things this is mostly gone today, although I'm certain freakish accidents can happen. Yes, if your hardware does not have ECC[1] that is something that can happen. I was initially surprised because I did not expect them to not have error correction, but I guess it makes sense for systems designed a long time ago and still in use, so that was new info to me.

[1] Technically EDAC is the correct name of the whole sybsystem, and ECC is the name of the algorithm. But I've only heard it refered as ECC in my industry. I was even initially confused when I read EDAC, so TIL.
