An airplane is much more complicated from a systems perspective (but yet can be more easily automated from an operational POV). To make an airplane fly, there are dozens of control surfaces, very complex mechanical systems, and not to mention a greater degree of danger (i.e., explosions) and loss of life should these systems fail. Yet, when everything "works" within their engineered/designed parameters, we can construct control algorithms around these operational envelopes.
Also, at 10k feet in the air, there are rules that govern flight paths (overseen by controllers); radar and beacons that help keep planes on track; and most importantly much less traffic/congestion (as opposed to a bus or car).
This provides the pilots (and also sailors) the ability to automate their flight at steady-state. This is where it gets interesting. If a plane loses a control surface or a critical system fails, these controls systems will be pushed outside of their operational envelopes, and this is where a human takes over.
It's not a question of "if" but "when" things will fail....
Whether these tools are just analog trim tabs that allow the stick to be adjusted so that a stable aircraft basically holds itself in straight-and-level flight, or complex fly-by-wire autopilot algorithms that keep an unstable aircraft in straight-and-level flight, taking the mundane, repetitive, mind-numbing workload of closing the loop between the six-pack of instruments and the sticks for hours on end. A pilot who has been watching the VSI and heading for three hours on a cross-country flight, tediously keeping the plane within 300 feet of its assigned flight level and ensuring that the passengers don't even perceive tiny changes in heading and attitude, or a trucker who has been driving their tractor-trailer cross-country for 60 hours in 7 days, holding an 8.5-foot-wide vehicle between a pair of 12-foot-wide lane lines, and adjusting the throttle up and down hills to keep their speed within a couple MPH of the speed limit, is going to be fatigued and when it comes time to deal with an emergency on landing or a sudden, unexpected brake check from a small car pulling in front of the truck, that fatigue has a cost.
There's a point where cruise control and autopilots can make these tasks safer, allowing pilots to keep ahead of the needs of aircraft, and allowing drivers to keep their eyes scanning the other vehicles, their mirrors, and the road ahead, rather than going back-and-forth between the speedometer and the lane lines. I absolutely acknowledge that there's also a point where this automation gets in the way or causes operators to tune out and be unprepared when asked to take over when the envelope is exceeded. Right-sizing that level of automation is critical!
Automation ==/== AI. Automation consists of a series of systems that are designed (i.e., programmed using control algorithms, logic rules, machine/deep-learning) to operate under a series of pre-set boundaries. The boundaries are typically defined under "normal" operating conditions, and safe-guards are put into place once the automated systems deviate from those "normal" operating conditions (I see a lot of practitioners esp. in the ML world fail to account for abnormal conditions...may be this is what happened w/ the Uber driver?).
The only comment I will say about AI is that I'm glad I am seeing RL and the like come more into play. I also contend this feels like a supervisory problem.
That’s not really what happens though. I also have some experience in automation. We humans don’t free ourselves up to do human things. We become slaves to the machines and automation. Yes, automating something frees up a human from doing the same thing, but when does it stop? The human just moves on to some other automation task in a never ending quest of scale.
People in a factory I worked in last week aren't gnawing furniture out of lumber with their teeth, nor are they whittling it with stone knives, sawing it with steel hand tools, or cutting it with power tools, they're loading and unloading CNC routers. It's not one person and $500M worth of equipment that lets a forklift operator dump logs in at one side and spit out semi trucks loaded with pallets of furniture, nor is it 2000 people and a bunch of hand tools, and it's about 200 skilled people and $20M worth of equipment. The most important feature of the equipment is the diagnostics, adjustments, and flexibility, allowing their operators to use their human judgement to improve operations.
We have declined a few of potentially profitable projects in the past year because we felt they were not a good match for our values, when customers had specs that required locking out operators from doing more than pressing "Cycle start", were unwilling to invest in training due to high turnover, or otherwise treated people poorly, or especially when they wanted to cut corners on safety, those are just not places that we partner with. This isn't purely altruistic, the effort invested in those undesirable shops is typically less valuable over the long term compared to the rising companies that treat their people better.
You don't want to have a human sticking their fingers in a grinder, or handling red-hot castings, or trying to install a washer on a dial table every 2.5 seconds for 8 hours straight, or attending the movement of a sewing machine within 1/8" for literal miles of seams sewn each day... those are all mind-numbing or dangerous things I've automated. But the machines can't efficiently understand when they're wearing out, they fault in a myriad of ways and need troubleshooting, they need someone to monitor the quality of incoming and outgoing product, keep them fed with parts, and to do other common-sense human tasks.
There are certainly things that people have tried to automate that didn't make sense. But there are a lot of things that haven't yet been automated which should be.
