South by Southwest Interactive kicked off this morning in Austin -- well, sort of. Can you really say a show like this has "kicked off," before a 3D printing CEO has given the opening remarks? Debatable. Thankfully, MakerBot's Bre Prettis is set to take the stage shortly to get this show started right. Join us, as the bespectacled exec talks about his company's role in "the next industrial revolution."
