Niaive to imagine that improvement in air safety statistics is due to aircraft automation and computerisation. As one who has flown older a/c Lockheed L188, B727, &737 classics, whilst more recently and currently A319/320 to me the biggest loss in the transition to the older aircraft to the newer is the loss of the flight engineer. Without a shadow of a doubt the greatest step backwards in aviation safety, IMHO.
I also had a spent quite a few years working in the IT industry before starting to fly, the statistics regarding logic - syntax - coding errors per line of computer instruction code would truly make your hair turn white.
Nonetheless, I have quite a few years left flying the minibus and it's degree of automation and computerisation doesn't particularly concern me, other things do but not that.
