My advice: If you have a 3D printer and you're inexperienced, get good at using it, learn to make the tricky sharp-angle funky-geometry bits.
If you have a shop and some metal, keep it handy, learn to machine parts on the fly if you don't already know.
If you have one of those silly quad-drones, get good at both modding and flying it.
If you have, say, a laser printer, learn the basics on how it works.
If you know how to build your own internet, sustain in an urban environment without power or running water, or provide ad-hoc medical attention, make sure your friends know it. If you want to learn to do any of it, start *now*.
Why? Well... if things start getting peaceful and chill again, you now have a new skill and a potential hobby for later, maybe even pick up some revenue on Patreon. :3
Maker culture is alive and well, but we could see it blossom, and in my mind amateur-stars may be entering something of a golden age. The information's out there you just gotta dig, and doing so makes it easier for others.
