Based on "The Veldt", what do you sense the author's attitude toward technology is?
The most superficial opinion that we might glean from this story is that technology is bad; it did, after all, lead to the deaths of the Hadleys at the hands of their children, which is a monstrous and shocking crime, particularly for the reasons that it was committed.
A more nuanced view might argue that technology, when overused, causes us to become less than human. This is evidenced by the elder Hadleys recognizing that they feel less useful than before, as though they have no place in the home. Their children, not having known life outside of the automated comfort provided by their technology, clearly lack a variety of human elements, many of which would and should have prevented them from killing their parents, and treating it as casually as they do. Technology has basically induced criminal psychopathy in the children.
I think it's always a bit dangerous and presumptuous to argue that an author's personal opinions can be inferred from their writing. While an author may or may not choose to write in a way that reflects themselves and their opinions, we are reading those opinions through a degree of separation from their origin (the author themselves). Thus, it is akin to hearsay, or speaking to a third party, to try to get insight about the author, when we could just ask the author ourselves. While this surely isn't an option for deceased authors unless they published these thoughts, in the modern world we have this luxury at our disposal, and the critical thought and analysis practiced by attempting to interpret the author's meaning might just as well be done by communicating with them directly. I've attached a link below to an interview with Bradbury where he says, in part, that the Internet is a "big distraction" - so we might assume that his views on technology itself follow that message to a certain degree.
