Да..., и human_robot никуда не годится... Уж скорее robotman... (но это уже зарезервировано ((как поняла из сети:)...))

This is an interesting challenge. Words like automaton, robot, cog in the machine evoke to me more the dehumanization of an earlier age (as portrayed in Charlie Chaplain's Modern Times, where he becomes literally part of the mass-production machine). The person doesn't have to know anything but how to do one repetitive motion over and over again, the whole day.

But the text we are considering is of a different character: the person does know things, even perhaps many things of a highly specialized nature, and uses them in his work, yet it is deeply dehumanizing, because his work does not summon up his fundamental humanity, and he has no conception of the world of which is tiny corner is just one part.

Therefore I tried to think of something that keeps the idea of human/человек in there.

This interesting quote is from the link below (emphasis added, although I don't think "learned ignoramus" is a good translation for your phrase):

[QUOTE]The specialist "knows" very well his own tiny cor­ner of the universe; he is radically ignorant of all the rest…. Previ­ously, men could be divided simply into the learned and the ignorant…. But your specialist cannot be brought in under either of these two cate­gories. He is not learned, for he is formally ignorant of all that does not enter into his specialty; but neither is he ignorant, because he is "a scientist," and "knows" very well his own tiny portion of the universe. We shall have to say that he is a learned ignoramus, which is a very serious matter, as it implies that he is a person who is ignorant, not in the fashion of the ignorant man, but with all the petulance of one who is learned in his own special line.
