The fact they didn't let the fetus grow really fucking sucks. Sure, ethics most definitely has its name etched on the science stone.

But people WILL without a shred of doubt recreate this experiment, and they most likely won't be as ethically inclined as the nice folks behind this paper.

The point am trying to make here is that we need to be prepared to deal with how a discovery like could influence our future. The best way to do that is to know what expect with enough time ahead to react.

And yeah sure people will say this is just an excuse for morbidly curious people like me to simply see what happens, and while I'm literally brimming in desire to know myself, theres a bigger picture, bearing witness is just a perk:)
