I could see a gigantic consequence of this being that people go online for the quick answer and people start losing the ability to conceptualize exactly what that answer means--they'll be so wrapped up in finding the right and narrow answer that their point of view in the subject matter will be greatly narrowed. I think we've seen it manifest itself already in the past couple of decades.
A great concept, this notion of mass cheating on an overwhelming level (or so it seems) when you're talking about passing a test or turning in a paper. But, in the long term, I could see this concept as being a tool to humanity's intellectual demise.
Not that there's any way you can stop it, I suppose. It's like a train that you see coming in the distance, and you're entranced by it like a deer in headlights and it seems there's nothing you can do to move out of the way.
I don't think for an instant that cheating kids get excited about learning new things. I think they're just trying to do what they can to get the A, and little do they know they're potentially trading out a little bit of cognitive enrichment pertaining to the subject on which they're so desperate for that answer to get that A.
Not to say I didn't have my own bouts with cheating back in the day (I'm only human). In retrospect, however, now I can see the bigger picture a bit better. And I can also see how it likely robbed me of some of the essence of the subject...and, if you're getting a degree in higher education, aren't you there because of a certain passion for the subject? In that case, shouldn't essence be everything? A physics professor of mine once said it best: it's not all about the answer, it's all about the journey.
I'm an advocate of the notion that you learn more when you fail than when you succeed; stumbling through to come to a wrong answer can be more beneficial than breezing through to get the right one.
