They also get rid of nearly all physical control cables and simplify control at the ECU level. It's far cheaper to use the same controller across 20 models vs a dedicated setup for each one.

It is virtually impossible for companies to offer direct linkage on the shifter, gas pedal, and hand brake anymore because of the way stability systems interact with the drivetrain. This is also why we are seeing electronic steering almost universally across the board. I wonder if we'll ever see a system where there is no mechanical linkage between the brakes and the brake pedal.
That being said, while not all tech is good, when it comes to headlights the new tech is so awesome it almost makes me wish we had more pitch dark roads so my headlights would get a proper work out.
With so much "light pollution" here in NYC, even remote areas are lit up from all the lights reflecting from the sky at night.

But those auto transmissions with 8, 9, 10 speeds are technologically superior to those old ones you love in every other way. I'll take an 8-speed modern A/T with buttons, dials or even mind control every day of the week over my 1978 3-speed A/T column shifter.

Current brake by wire systems have a valve that opens automatically in the event of system failure to allow the hydraulic system to be activated by the (not normally connected) brake pedal. The Brembo system will likely be one of--if not the--first to eliminate the hydraulic system completely.

Well, your premise is off. I don't necessarily love older transmissions. Three-speed non-overdrive automatics, IMO, didn't match well with small four cylinders......even in high gear, the engines simply spun too fast once you got up past 60 MPH or so on the Interstate. And the four-speed overdrive transmissions had too wide a ratio between third and fourth. We didn't really see some decent compromises, IMO, until the five-speeds.

In the meantime, just a hypothetical question.......would you want to be one of the Guinea-Pigs that actually tests the long-term reliability of those brake-by-wire systems in customer-hands?
I'm not sure I'd want to be...look at what is happening with some Teslas and their overly-advanced driving systems.Several years ago, for example, when I reviewed a new Infiniti Q50, it was one of the few vehicles in the American market (perhaps the only one)? to offer the optional Adaptive Steer-by-Wire system (with a so-called emergency manual back-up). I was nervous enough of that system that I deliberately looked for a Q50 with the conventional steering before actually taking it out on the road.

100%. My 04 Runner had some brake line issues. And last summer there was slight seeping of the power steering lines as it came out of one of the coolers. My mechanic just bypassed the direct line and added a solution to correct the problem. I think the electric power steering is the way forward, I'd have no issue with it in the next gen 4R which I am sure will be electric motor for the steering. I would be happy if the fluids were gone. No hydraulic systems will help with fuel and power efficiency as the engine now longer has to power the steering system in the same way.

As cars become more autonomous you need electronic control systems.

Autonomous stuff and stability stuff become part of the same thing as they become more sophisticated. If you have a system that modulates power, takes over braking and steering in certain situations its much easier to accomplish that with electronic systems than manually actuated systems.

I wouldn't say its cheaper at all, its cheaper to maintain but cables and hydraulic pumps are pretty cheap compared to sensors and computer modules.
