There are many uses of modern computing equipment on board aircraft today which simplify a pilots job and have contributed in a shift of the traditional pilot role to that of a systems monitor for more of the time than used to be the case.
Flight Management systems, electronic instrument displays and right through to the latest Airbus and Boeing fly-by-wire systems incorporated on recent developments have all played their part in making the job easier for us in the front office, and safer for those in the back.
Computers and computer logic are behind advances such as Ground Proximity Warning Systems, TCAS, Flight Envelope Protection, etc... all of which contribute to enhancing the safety of commercial flight.
I know many pilots who fly the latest fly-by-wire aircraft like the A320 and they don't feel less "in control" of their aircraft just because there is no feedback from the stick. Military pilots have done it that way for years so it's about time we did as well.
That was just a brief rundown of my opinion on these matters, but basically there are more pros than cons I think. The safety benefits are far too great to ignore just because some pilots still love their DC-9s!
I used to love the smell of Jet-A in the morning...
