Yes, some of these statements have absolutely no scientific merit. I dont think that it helps the development of the feild to make strong statements, especially about the efficacy of different technologies, unless you actually understand them. This could have a very seriously detrimental effect on particular companies and it is irresponsible. I think that your area of expertise is in marketing and conferences, which has been a great addition to the field, but to make pronouncements on technologies that you dont understand is inappropriate.
