There’s a case to be made either way. At first blush, one might think that there is a certain irony in posting this question to the internet in hopes of receiving answers rather than just answering it yourself. Indeed, someone might say that you’ve answered your own question just by doing so. You are now at leisure to let us discuss the issue amongst ourselves, picking out the parts of the conversation you like and relying on the people you trust to come up with good points. You’ll even get to see objections and replies without having to come up with either on your own.
I agree with @longgone, however, that access to information does not discourage thinking or encourage complacency. Of course, the original question was about instant access to information.—the idea presumably being that asking on the internet is a lot easier than figuring out which books to look at—but I do not think this has to make much of a difference. We must therefore figure out what is wrong with the original assessment.
For one, it is entirely possible to be complacent about the information one gets from books. I’ve had students who clearly went to the library, pulled down the first book on the topic they could find, and just copied the ideas found therein. There’s no analysis of the ideas, just heavy reliance on the assumed authority of a single source. Students who do this seem to be under the impression that if someone smart said it in a book, it’s probably true (ignoring the fact that intellectual discourse involves a bunch of smart people who can’t all be right disagreeing with one another).
For another, just as going to the library does not prevent one from substituting someone else’s opinion for one’s own, going to the internet does not require one to do so. In part, it depends on how you use the tools you are given. Going to the first site suggested by Google and just parroting what is said there is one strategy, and it is more or less the same as pulling down the first book you find and copying it. But it’s not the only strategy.
In a library, one can pull down multiple books and get a sense of a field’s diversity. Using the internet, one can load multiple sources and again receive access to a diversity of opinions. Alternatively, one could do what you did and bring the query to a discussion site. Discussion is a longstanding way of generating ideas to pick through. And there’s the rub: to do this well, one must actively pick between competing options and opinions. That’s what’s wrong with the original assessment. Even if you don’t participate in this conversation, you face a choice between just copying what we say and thinking about which parts are worthwhile.
In short, every source of information provides an opportunity for complacency. But by the same token, every source of information provides an opportunity for active thinking. It is a matter of the student, not the student’s resources.
