I think there is room for all-both mainstream and alternative, but I do believe alternative is growing and since research supports many of these treatments and techniques, then soon medical schools, etc will have to start including this information. Medical doctors could incorporate these techniques into their practices and help people to wellness rather than just treating the sickness.
I would like to see a time when medical treatments aren't even necessary because people will learn about health and wellness and won't even have illness and disease.
