Scientists Grow An Even Better Replacement Human Ear

So I have to ask, this research they are discussing is only talking about the physical ear shape? Not the function of the ear?

The idea of growing a body part off an animal just seems archaic... today. Scientists have gone much further with  3D printing of ears with living tissue, which included a video of the process.

This link has a video of a scientist discussing what they are currently doing

And the ability for these ears to actually function.

Hey, I love innovation and anything to improve life, but these guys are discussing what seems like old technology.
