It’s interesting that Philip K. Dick’s androids from Do Androids Dream of Electric Sheep? and the Replicants from the Blade Runner are way closer to Čapek’s robots than to mechanical humanlike contraptions. All three raise the same question — what is humanity, when you really get down to it?
And the (non-Dick) movie sequel 2049 makes it even closer given how it is revealed that (some) replicants, just like some of Čapek’s robots, can become pregnant and give birth just like humans, allowing them to continue without humans manufacturing them.
