None of those are something that you as a programmer should ever worry about.

Counterpoint, I have definitely taken them into consideration when designing my backup script. It's the reason why I hash my files before transferring, after transferring, and at periodic intervals.

And if you're designing a Hardware Security Module, as another example, I hope that you've taken at least rowhammer into consideration.

I consider these all the time as a programmer. Particularly compiler/toolchain bugs, which are relatively common once you start looking for them.
