To understand aviation and the professionalism and the interface between human and machine, people need to read Flight Discipline written by Flt Colonel Tony Kern whom I have met.
He was a B-1B Strategic Bomber Pilot (USAF) - Multi Crew. That's very important. Military Multi Crew pilots are well trained.
I have been blessed to have also completed most of my flying in a multi crew environment and I am also blessed to be an old school stick and rudder guy mostly on Lockheed aircraft.
I have flown many types - currently fly a Challenger and the automation does exist but you can only use the automation in so far as the FCOM or company SOPs allow it. For instance, our company forbids an instrument approach in NAV Mode and VNav Mode. You got to hand fly it. It maintains pilot proficiency and keeps the pilots proficient and maintaining their discipline. Tony Kern talks about this quite a bit.
Boeing aircraft, including the B787 Dreamliner has all the automation of Airbus, but they allow airlines to set their own policies with regard to their own FCOM and SOPs. You can hand fly the thing all the way if you want. Can't do that in an Airbus.
Automation does not reduce accidents or remove human error. In fact, the evidence is that it has the opposite affect and that it brings in other dangerous elements such as loss of Situational Awareness, complacency, and also modern pilots such as the First Officer of the Ethiopian Airlines Max 8 not being able to fly as well or maintain a good Instrument Scan. They probably only fly an instrument approach once every 6 months in the sim. I fly instrument approaches about 10 times a week even in CAVOK we are given a STAR and ILS Approach which we hand fly, albeit 2 crew in 2 distinct roles - Pilot Flying and Pilot Monitoring.
One time, I had to evaluate a Pilot from Korean Airlines in the simulator for a job. We got him to do an Non Directional Approach at Cairns, QLD. From the outbound to inbound teardrop turn, the guy turned the wrong direction. In real life, the consequences of this wrong turn would be disastrous as there is high terrain in the vicinity. In treal life, the FO would have called for a Missed approach.
The reason for the error: it wasn't because he was a bad pilot. On the contrary, this was an extremely experienced guy flying for Korean. He lost SA and he also failed to use the second pilot to shed his workload.
So there are 2 trains of thought. Boeing is more stick and rudder for now.
Airbus is going full automation.
My preference is for Boeing. They fly better and in my opinion are a lot more safer because pilots are better trained, get more stick time and have better SA.
There is no replacement for multi Crew pilots. This is what makes aviation the safest transport system in the world. Its the pilots, their professionalism and their discipline. It's not a computer. We already have the technology to eliminate the pilot altogether in faour of land based operators like the guys that fly Predator Drones from a ground based station on the other side of the world.

Pilots are the only cog in the wheel that can manage a cockpit crisis.
Additionally, it is extremely important for pilots to maintain sound Aircraft Systems Knowledge. It's important to understand every component and system on the aircraft you fly. Your life will one day depend on it. pilots do have a lot of knowledge and as much knowledge as an engineer does, the only difference is the allowable maintenance that can be done on the 2 different licenses.
