As one who has studied entomology, especially Biological Control; I am aware that there were faulty methods of evaluating suitable insects for attacking imported pests. The USDA has stricter standards now for evaluating host specificity (how likely is the critter going to pick on a native vs target insect) of a biocontrol agent (= phorid flies in this case).
True, in the case of ants, since there are so many species, foolproof bioagents can be difficult to get, but there have been successes too. I personally have worked with Cereal Leaf Beetle and the complex of wasps we used to control the critters have successfully kept them in check...and kept wheat production costs down.
I'd Mod you up, but I already commented. Same vein as "Blu-ray will be irrelevant because we'll get to download everything."
Think "Pay-per-view". Thanks, no.
...are a strong wind to blow them away...or their local power grid to drop out. The infrastructure is discussed even less than data security.
I'll keep my Windows/Linux/Mac fat clients, TYVM.
