Do EDI and the Geth die at the end of the game if you choose to destroy the Reapers? (In case you let the Geth live in the first place, of course.) Or the only option to keep them alive is to choose one of the other endings?
EDIT: I've read the answers and if all synthetics are destroyed, how it is possible that Shepard manages to survive and the Normandy keeps flying (at least long enough to crash-land on some planet)? I mean is the destruction of EDI/the Geth certain or only assumed?
