A novel threat to high technology

[JohnnyYesterday]

You can't print new things cheaply without also having some way to break them down, otherwise your house fills up with things or the world fills up with garbage dumps. There's a monetary incentive to breed bacteria etc that can break down our products, whatever they are. It'll always happen, and we'll make it happen faster in the future.

Eventually everything that gets constructed will include an RFID tag or such, and an internet database will link that tag to how to deconstruct that product. Also how to construct a second copy. That solves the problem of accumulating broken junk that you don't know how to get rid of.

Plasma gasification is really effective, so there might not be as much of a need as you think.
