"It is a symbol of Irish art. The cracked lookingglass of a servant." -- James Joyce
I just read Isaac Asimov's Fantastic Journey II -- not a bad book, about what you'd expect from Asimov. (Yes, 350 books is fantastic output, but quality does suffer a little along the way.) But what really struck me is that Asimov, writing in 1987, saw the USSR still around 100 years later, still operating much as it did in 1987, just a few years before its complete disappearance from the scene.
