I mostly talk about things of a technological nature here, well, that's really ALL I talk about as it is the focus of this blog. But it's not often we see in detail how technology is capable of impacting lives on a very dramatic scale in both human and animal recipients. I run across a lot of things on the internet regarding these types of things and one of those things is a lot of people's fear of the unknown. It's a natural human cognitive response, but we should always strive to understand something and educate ourselves on it's purpose than to immediately condemn it out of fear. In this instance I'm referring to 3D printing. It goes without saying that people are going to explore this newer technology to see exactly what it's capable of doing. It is our basic human curiosity to do so. 

Sometimes that curiosity pays off in a big way. 3D printing is opening the door to amazing possibilities in prosthetics, tools, and other tangible objects. Nasa just emailed a wrench to the international spacestation! We can literally email someone the blueprints to a particular item and then "print" them so to speak to serve their intended purpose on the fly. This doesn't invoke any feelings of fear from me, but instead opens another avenue of dynamic creation and excitement. That same excitement exists with nanomachines in my techy mind. But here is a great example of how something like a 3D printed image changed a life in someone's canine companion and how this will pave the way to many other life-changing experiences for many others in our own species. Imagine a human being able to walk for the first time. Run for the first time. Climb for the first time. Mobility is coming, and it will be affordable in the future to everyone.
