It's just a matter of seeing results in a more direct sense.

If people can somehow figure out how to achieve consistant results from the 'mystical' powers, and it becomes something one can get educated it easily and at a decent speed, then it won't be a matter of belief but a matter of fact, like internet.

For example 'send me a this image from your phone to mine over wi-fi' and the results show.

So, once we reach 'send me some good energy, i'm at work and kind of depressed' then that's that.

Right now, we have basically low-level knowledge (it least for the masses) regarding energy transfers from one human to another, and by that i mean hugging someone you love, being around friends you're comfortable with, and so one, the good vibes we get from them are strong but very short range, and that's why we sometimes use a transfer medium which is the internet for example to expand the range of those viberations/energies.

That's what I think anyway.

Let's hope we can figure out ways to meaningfully expand (and know about it / see its results well) without such technological transfer mediums.
