Totally different systems I'm sure......I am not personally familiar with modern automated systems/flight directors, but I think the root issue is the same.
In my aircraft, you will occasionally get a plane with malfunctioning auto throttles....normally one throttle just can't keep up with the other and it kicks offline. Unfortunately, there is no caution tone or anything, and the only indication is a flashing "ATC" cue in the HUD. So if you aren't looking, ie busy doing a bunch of other heads down mission related stuff, you can quickly find yourself at 115 KCAS and about to fall out of the sky. Granted this airplane is very very difficult to depart, and unless you are completely out to lunch, you will notice how cocked up the airplane is and quickly jam the throttles forward. But I think it touches on the fact that with all these fancy gadgets in the aircraft to monitor and derive information from, it is very very easy to lose track of the fact that your job is still to actually fly the airplane. Whether that be by hand or by some sort of pilot relief mode, does not relieve the pilot of the ultimate responsibility of ensuring the airplane is still at the correct airspeed, altitude, and navigating to the correct place. Just something that I think a lot of people forget about when they move into fancier flying machines that can do more for you as the pilot.
