Alternately, though this may be stretching the point, you could say that '60s AI-as-human was at the _end_ of its curve, shortly to be replaced by the more practical actual AI. While specific writers have different biases--and some end up way ahead of the curve--in the aggregate I think futurists tend to overestimate the technologies of their era.
Though you're definitely right that literary biases play into it. While not not all SF writers are futurists, most futurists are trying to tell stories. Even some who aren't primarily SF writers: Kurzweil has a narrative arc to his ideas.
