It isn't about the software. Ofcourse voting software can be made reliable. But how do you trust they are reliable? How do you verify them? How do you verify the surrounding systems? It is a dead giveaway if planes start falling out of the sky that something is wrong. Not so when someone steals an election. If you want a good password hash you don't go for a fast hash that can be implemented in hardware. You go for a really slow hash that is hard to compute. I think this worse is better approach applies with voting systems. You really don't want them to be efficient. Optimising for efficiency takes away some of their other good properties. Paper voting is incredibly inefficient compared with machines and that is why it is so appropriate.
