I think it is a comment on the tendency of human minds to model complex systems as simple ones and therefore stick strongly to a few remedies whether they are sensible or not - ancestrally "whack it with a club" but in the case of computers, "reboot it", "run the virus scanner" and "defrag it". Admittedly, for old computers that relied on vacuum tubes whose connections would sometimes work loose, "whack it with a club" did, in fact, occasionally work.
