In Fahrenheit 451,what does Bradbury reveal to his audience about humanity through the irony conveyed by Clarisse?

Bradbury uses Clarisse to express that
humanity as we know it is on its way to being extinguished... just like
Clarisse. All those things that made Clarisse alive  (the ability to appreciate smells,
sights and sounds, the ability to think and ponder, the desire to learn) were values or
qualities that the society either frowned upon or moved away from because they all had
something to do with feeling or thinking. As readers we like Clarisse and her affect on
Guy, but as the storyline continues we realize that she just vanishes. It's ironic that
this happens to her because this is a part of Bradbury's message. If we do not do
something with the way that technology is robbing humanity of thinking, feeling, and
relating, we too are on our way to permanent extinction. It is a dreary message, but
certainly touches readers closely as they consider how lazy behaviors and attitudes
affect them.
