Bad memory maybe? I also have much less trouble with my personal Macs than my personal Linux boxes (although I push the edges on beta and cutting edge software a lot more on linux, while I treat the MacOS as something I can ignore the versions of, unless they notify me to upgrade). But haven't had a abrupt reboot outside of software updates in forever (on personal macs - work mac reboots at IT's whims).

I haven’t seen a crash in at least a decade of daily use.

Back in the older Intel days I did sometimes, perhaps due to the GPU switching and flakey Nvidia drivers. But even then it certainly wasn’t common.
