As Clifton Fadiman says in one edition of The Martian Chronicles Prefatory Note: "Mr. Bradbury has caught hold of a simple, obvious but overwhelmingly important moral idea... That idea--highlighted as every passing month produces a new terrifying lunacy: sputniks,super-sputniks, projected assaults on the moon, projected manned satellites--is that we are in the grip of a psychosis, a technology-mania, the final consequence of which can only be universal murder and quite conceivably the destruction of our planet." Bradbury's paradigm was very different from those of his science 'fictioneer' peers. Since humanity has not heeded his warnings, let's hope his dire prophesies do not come to pass.
There's a fascinating interview about Bradbury posted at The Paris Review: Ray Bradbury, The Art of Fiction No. 203. Check it out!
Rest in peace, Mr. Bradbury.
