I think that in general, that statement heralds from a time when
components had approximately equal failure rates, and it's gotten
more complicated since then, especially with parts that contain
so many individual subsystems that partial failures are possible,
and those can be a lot more complex to detect and analyze (thus
the multiple-copies with voting systems.)

Alas, with anything containing a computer, the proper maxim is
likely to be "more lines of code, more complex = less reliable."
