A chilling vision of the future, where phone books and checkbooks still exist ;)

I have the impression that nanotechnology was very in vogue for science fiction around the late-80s and early-90s…and yet, these days, it’s seemingly disappeared; both as a sci-fi trope and, AFAIK, an area of industrial/medical R&D. Why is that? Did it just atrophy, perhaps combined with unmet expectations, or did we discover some limit that makes the technology infeasible?
