I am sure the importance of the internet can't be overstated but I'm not as sure that it will have much effect on how people think about what they consider "science".
Up until I got interested in the pyramid it never occurred to me that all branches of science were well founded in theory. Sure, I've always had a lot of doubt and considered most science whose variables can't all be quantified to be speculative. I knew that most of the softest sciences like Egyptology were constructs more than actual science. It just never occurred to me how little basis and how little science was actually involved. It never occurred to me that they wouldn't employ all the tools of science. It never occurred to me that it was more about careers and building on existing thinking than it was about discovering the truth.
Even though I know wiki is always wrong it's still the first source for almost everything I research when I know nothing.
I suppose younger people might be wiser in their ability to use the net to find information. I do hope you're right and hope that younger people use some critical reasoning before accepting anything they find on the net. Some of the alternative stuff is as far out there as orthodoxy.
It all makes me wonder how much truth is in all those other specialties that I'll never find the time to investigate. The net just might be the game changer to upset some of these paradigms.
