I think that is part of the problem. Hey, I'll be the first to jump on the equipment bandwagon, strictly because in order to capture indisputable evidence pure fact of the matter is that we have to deal within the physical world cause that's where most of us live exclusively.
But you're 100% right, it should never become the focus but rather a tool. The focus should first and foremost be to help the living and those who have passed. Dispute arbitration! Help those cross who need crossing. And as was brought up before here before, investigate in a way in which it minimally impacts the residents. (Living or Not)
But technology does have its place. Its all still very much an evolving field. And I think one reason you're seeing more people jumping on the bandwagon (aside from that its now plastered all over TV) is that its no longer a field of study in which you have to take someone's word for it. Now there ARE ways to document things, and more are starting to emerge constantly.
We're all just youngsters delving into an old question.
