Computers have most certainly helped pilots to operate aircraft because he or she now has much more capacity to cope with the role rather than the flying. However, although this spare capacity can also be used to fly safer, the computers cannot change the basic equation - flying is inherently dangerous and aircraft don't always meet the ground in an agreeable fashion.
Having accepted the usefulness of computers, should they be given more control of basic flying functions? I think it is important to consider why before designing more computer-reliance into an aircraft. If it is not going to confer an advantage why do it?
