Out of sight out of minde."
The phrase is used as an example of the supposed comic results that early computer translation and speech recognition programmes came up with. The phrase 'out of sight, out of mind' was supposed to have been translated by a computer as 'invisible idiot', 'blind and insane' etc. This is on a par with 'computers can wreck a nice peach' (computers can recognise speech), which is also used as an example of how computers lack the general knowledge to compare with humans at speech recognition.
