[citation][nom]Spike53[/nom]By your reason, we shouldn't have cellphones even though scientists have already disproven that it has any negative effects on cells, but we should err on the side of caution.[/citation]Your comparison isn't relevant. On one hand we have a new type of glasses-free 3D display, which the manufacturer of says may be bad for young, developing minds. It is a new technology. On the other hand we have cell phones, which have been around for a long time, and which we understand very well. In particular, we understand things like the type and amount of radiation they emit. By the way, their output power is limited by the government.
So then, tell me all about the 3DS screen tech, how the brain interprets the light information emitted by the device, and what effect this has been proven or not proven to have on developing minds? You're right, why bother with studies! Here you go kids! Fuck it, right?
