Graue-Schmia
Graue Schmia bzw. Graue-Schmia-Szenario (dt. Graue-Schmiere-Szenario, engl. grey goo) is a hypothetisches Szenario vom Wejduntagang afgrund vo molekulara Nanotechnologie. Vauasocht sois duach sognennde Nanobots wean. Des san kloawinzige Assembler, de wo si sejm reduplizian kina.  So wead de gsamte Materie vo da Eadn afbraucht, um imma meah Kopien z macha. Ma nennt des Szenario aa Ökophagie, wei de Wejd vo de kloan Robota sozsogn afgressn wead. De uaspringliche Hypothesn wor, dass de Roboto scho so konstruiad waan, dass sa si sejm reduplizian kina. Andane vamuatn, dass se de Funktion sejm dalanga kunntn.

Grässane sejm reproduziarade Maschina san uaspringlich vom Mathematika John von Neumann bschriebn worn. Da Ausdruck Graue Schmia bzw. engl. gray goo is vom Nanotechnologie-Pionia Eric Drexler in seim 1986 daschienanan Buach Engines of Creation eigfiaht worn. 2004 hod da Drexler gsogtz: „I winschad, i häd en Begriff ‚gray goo‘ nia gnuzt.“
