Why are you comparing a tool used for knowledge and action augmentation to weapons created for destruction? Because your statement would look dumb if you said "electric motors and encyclopedias" instead of "neurotoxins and bombs".
I can use both electric motors and encyclopedias to inflict mass casualties against people who refuse to use them or the results of their labor, but that doesn't make them like bombs and neurotoxins. You're simply scared of a new technology because it's so different.
