Short answer to the lede: no, the industry cannot cope. Or rather, it will limp along with bloatware, bugs, and malware exactly the same way we see desktop OSes bloat, or the way we see routers and set-top boxes hacked to become botnets. In my 40+ years in the industry I've yet to see code get SMALLER. With the exception of Linux kernel 1.0 in the 90's which was a step backwards into smaller, more compact code, code…
Three knobs: temperature, speed, vent selection. Three buttons: a/c, recirc, rear defroster.
That's it. The entire system. It's a 20 year old design at this point. I have never once thought that I, a mere mortal, could improve on the design in any meaningful way.
The buttons and knobs are big enough that I can work them w/ my huge gloves on, I do not need special gloves that work w/ a touchscreen, the buttons are not context sensitive, and I can hit all the controls in the dark without even looking. Another point, which I've now learned I had taken for granted, is that no software update will ever mess w/ my muscle memory. Those switches cannot be programmed to do anything else in software, as they're physically wired to the functions they control.
The beauty of the system above is that the physical controls are the state machine. I can literally feel the state the HVAC system is in. Nowadays that state machine is all in software, and I have to hunt through menus, look at a display, sometimes multiple displays, just to figure out what state I left the system in. That's just unacceptable.
