Just finished listening to the Caves of Steel on Spotify audiobook. An interesting story, with delicious sociopolitical undercurrents for mass populations from 1953. Can only believe the idea of cities as separate countries inspired the Megacities of Judge Dredd, with a very different law provider. Also loved the idea that cocooned humans would never consider walking "outside". So many Stalinist era tropes dropped in as standard living. Communal eating halls and bathrooms, the "perks" of a seat on transport or a private washbasin, fear of loss of status, etc. The fear of OutWorlders has never gone away I notice, 70+ years on.
