I can see it now...
Currently -
Both pilots get food poisoning, are ill, hostess comes into cabin "Can anyone fly a plane???"
In 20 years time -
Computer gets Blue Screen of Death, hostess comes into cabin "Can anyone program a computer - to fly a plane???"
Maybe not in twenty years time but eventually the answer will be;
Passenger comes forward with his own computer..."No, but this computer here can fly the plane."
