There's another side though. Do you want to see pseudoscience stem cell "therapies" sold on late night infomercials as a panacea? A balance has to be struck between the number of people that could potentially be helped and the number of people that could potentially be harmed. We can debate how this balance should be struck without assuming bad faith on the part of those that disagree with us.

On the internet, when startups overpromise, misrepresent, and take risks, the worst that usually happens is that a few million people lose their data or get their embarrassing photos shared with their coworkers. In health care the consequences of an overhyped technology are far more grave.
