A lot of love here for A Fire Upon the Deep (predicted fake news via "the net of a thousand lies") and A Deepness in the Sky (great depiction of cognitive enhancement, slower-than-light interstellar trade), but less so for Rainbows End, which is perhaps a less successful story but remains, after almost two decades, the best description of what augmented reality games and ARGs might do to the world.
Predicted ? A Fire Upon the Deep published in 1993, at which date Usenet was already mature and suffering such patterns - although not at FaceTwitTok scale.
But still, I love Vinge's take on information entropy across time, space and social networks. A Deepness in the Sky features the profession of programmer–archaeologist and I'm here for that !
