>yet everything we actually need to survive is intact.

Unfortunately we now rely on our machines to survive. If they'd suddenly disappear, we'd have a bit of a massive problem. We just wouldn't do very well without our heavy agricultural machines, our food and fuel supply systems, our water pumps, our fertilizer plants, etc. We're not going to feed 7 billion people without machines anymore, so we'd better fix them fast or risk losing a lot of us.
