Don't say Digital Circus or I'm gonna cry and kms

Maybe dragons would hoard old tech from dumps. Use their fire to burn away the plastic and glass and leave only the small amounts of gold used for circuits.

Then there's just the dragons getting more and more furious as society moves away from gold as a currency. Before, they could burn down a kingdom and plunder the gold after but now, burn down a city and all they find is stacks of paper and plastic disks.
