I'm not SPAM Google (nor will I be Soilent Green) but somehow Google thinks I am a SPAM robot and it is threatening to shut down my nascent blog. That's the problem with technology: algorythms can only do so much for you before you need intellect and reasoning. No AI will work here, just old school intelligence.
I think the same goes for librarians. There is only so much that technology can do before you need a human.
