I just think it would be a very odd world if there were articles written in that style, by science writers who appeal to the mainstream non-scientific audiences, about every novel technology (eg "iPad to make you stupid !!"). And I don't think that link is really enough evidence - perhaps if the data was public it could be?

In any case, the real issue with 3d for me is the eye strain - won't that be more of a hazard then temporary depth perception? (I have no evidence, just a headache).

Obviously? how did I imply that? My point was that it would be nice to have more solid evidence in articles to avoid people turning into quivering messes at the potential danger of every technology. Or course we should have caution.

I am a bit sensitive about this general issue (nothing to do with 3d) as there have been quite a few deaths in my area in the last year due to people's fears of radiation from mobile phone towers (which are in fact no where near their house, but that is another issue).

interestingly, the Amish attitude to technology is to initially reject until they see that is both safe (physically) and enhances their values (pretty much the opposite to everyone else). I find that interesting, but I can't find the link to the article that talked about that.
