I'm reluctant to be more critical because i dont know more about their work and the costs involved but...
From how they describe what happens (in your interview with them), basically it is a certain frequency they tap into which brings about a certain state within the brain using stroboscopic lights technique. I've used a "mind-machine" before - it didnt cost 18,000. It cost £130 at the time.
I have a question though - Did Dr. Engelbert Winkler and Dr Dirk Proeckl *patent* this particular (or set of frequencies depending on which type of experience you desire) frequency? If all it is is stroboscopic lights pattern/frequency then it is something you can program for other light-based mind machines.......hrmmm. So what happens if someone buys one of their machines, is able to decypher if you will the frequency required and then merely programs this into something like a Proteus mind machine.
I'm just speculating as i have not seen Lucia in action.
So naturally this makes me think very poorly of them (of course i could be way off base here). The huge cost for something that is merely a light pattern gives me the impression that they are exploiting people for profit...for money not advancement of human knowledge. Whatever happened to the pursuit of science to increase knowledge and understanding of the human experience..it seems to be "science for sale" instead.
If they managed to isolate the specific frequencies for the types of experience (extreme relaxation, different meditation states, obe) then they could have sold this to mind machine manufacturers perhaps?(Instead of creating only their machine (Lucia) which could produce these experiences).
Or is this too dangerous? That is, too dangerous for the consumer market but ok to have in medical departments with trained practitioners operating it.
Much of what i am saying is speculation, just thinking out loud. So dont crucify me for asking questions
