Now, there are many different Zombie scenarios, but I can understand why you see Zombies corresponding to a fear of loss of technology. Although I always took the fascination with Zombies as:
(besides being the "post-apocalyptic scenario" where you have to figure out how to survive)
- a fear of losing individuality/being slave to society, or the sort.
- people feeling others in society are some sort of "monster" or "animals" consuming each other,
- which makes people feel frustrated, creating a schism between wanting to see it all destroyed (especially if you're a "forever alone"), but at the same time seeing those that reflect what you are/were and your friends and loved ones, becoming something else; join them or psychically "kill" them ("disconnecting" the bond).
And the end product (hitherto): stories about it (or a proletarian revolution?).
Regarding "Also note whose skills become fearfully useless in the Zombie apocalypse - the programmer."
Dude. If the dead starts walking and your worries are finding a job then maybe your problems lies elsewhere.
... Code. Need to code...
