Bradbury shows that putting too much trust in technology is dangerous by showing a society where it takes precedence in actions.

Explanation:

Ray Bradburry had been one of the foremost authors of science fiction that had been writing for people to understand that there had been issues on machines and technology that the people do not understand have more to do with human consciousness and its trust on the things it is subordinating to itself

This belief can lead to the downfall of humans as they would rarely consider all the things they must consider about the machines and end up being ruled by machines they made.
