Yep, this is what is so great about tech advances. In the next few years so many people's lives are going to be made better off. In the next few decades, the majority of the planet will be living lives they deserve to live, free of chronic ailments, starvation, and poverty. 3D printing will play a huge role in all of this in my humble opinion.
