technology and transportation

His masterpiece 'Metropolis' (1927) visualizes a dystopian future dominated by technological infrastructure and urban transportation systems as central to class struggle.

His films like 'Snowpiercer' (2013) and 'Okja' (2017) use transportation and technology as metaphors for social hierarchy and humanity's complex relationship with innovation.
