There were "aids" to help a pilot fly the aircraft.
What is happening now is the pilot is becoming a systems manager, completely different.
A couple friend have just returned from NZ. Had an enjoyable ride in their mate's car, a Tesla.
Except on one trip. Up and over Arthurs Pass, no less that three "phantom braking" episodes occurred.
How long before we see a phantom missed approach?
You're comparing a Tesla, which doesn't undergo the same rigors of testing and is not held to the same safety standards as an aircraft, it's like comparing apples to oranges. Not to mention that we always seem to forget that Aviation is built on mistakes, things we didn't see coming but probably should have and ultimately will continue to be made on mistakes. Things like the Comets that broke up mid-air, early INS that got people lost and way off course are classic examples. Will there be issues with early fully autonomous Aircraft? Almost certainly, but like anything in Aviation we don't choose to not innovate because it might be risky, we innovate with this in mind and do our utmost to prevent it and mitigate it.
And ultimately a big part of that mitigation is having Pilots that fully understand the systems in place and what to do when they don't work as intended and making sure they perform those actions correctly and decisively.
