Not Gibson, but Snow Crash comes to mind
I mean, obviously we're not going to see a physical virus that enters as sensory information --
Wait. ... Are COVID and anti-masking part of the same replicator-complex? ... I see how anti-masking helps COVID. But how would COVID help anti-masking? I don't see how. ... Ok, probably not.
-- but that book's concerns seem incredibly prescient.
What disturbs me most is how L. Bob Rife, the bad guy, in his one and only monologue, in a TV recording (weird how he never appears in person), seems to... basically be correct.
Biomass.
I read Snow Crash about two years ago and the theme of virality increasing as dynamic systems get larger feels all too real right now.
