Rocketry is fun. Those 3D printed munitions are for sure going to be a thing. Also as soon as the first serviceable spec design comes out at least one person is going to blow themselves up. That will be a weird day where the Republican Pro Gun folks will have to legislate or dig in for freedom to own everything up to DIY nukes or whatever, just swing the other direction. That seems more likely than anything. And then the Democrats are going to be frothy to push all sorts of gun control to address it but also get the things they've wanted related to regular guns and then they are going to get into what is involved and they are going to have a really, really hard time solving that problem because you know.... Regulate 3D printers, files anyone can have or transmit, or the material components to make it work which are as numerous as the stars in the sky.
Wow. What the internet did to/for us is so weird. We live in a very weird time.
