Short SF Stories, Tales for Technophobes

Sentient beings who refuse to accept that they could have evolved from such lowly origins as the primeval slime often end up surrendering to their own technology. From supercomputers that control Earth to plasma beings created to protect space museums, there is always that glitch which compels them to think again. And what hope do the electronically dependant, who expect nanobots to clean their fingernails have when confronted by a moon-sized greenhouse occupied by voracious vegetables hunting for new pastures, or a monster munching its way through the fairyland characters around which their lives revolve? Survival does not necessarily depend on the fittest.
