Smarthome - General question of meaning

And what I find very interesting is that many people consciously decide against a smart home, but drive a new car where a lot of special equipment is mandatory. There is Keyless-Go, so you no longer have to take the key in your hand, the climate control regulates the temperature, the convertible top opens at the push of a button, the headlights stay on for 30 seconds after leaving the car to illuminate the path to the front door ... These are extras for which we are willing to pay a lot of money. I know not everyone has these features, but meanwhile a very large part does, and even in used cars one enjoys the gain in comfort. And something like central locking and at least the remote key and air conditioning is installed in almost every car, even older ones. I sit in the car about 1.5 hours a day (and I claim that is more than average). I spend much more time in my home.

Yes, me. I don’t know a world without phones, but certainly without mobile phones and without the internet. I would like to go back in time. I can’t say that my mobile phone use makes me happy. It’s practical. But that’s something different from a real benefit.

Why do I sell my car again after a few years? I can also drive my car until it is no longer economically feasible to repair it.
The reason why a new car comes is probably less often that the old one caused problems that are too difficult to solve.
And you have the choice, you can also drive a Dacia with basic equipment. Or drive an oldtimer as an everyday car again, it’s not that much fun anymore (I’m a big car fan and also drive oldtimers, but only for fun, not daily)... No central locking, searching the radio frequency with the rotary knob, using a map instead of a navigation system, etc. Nobody can convincingly tell me otherwise. I myself drive comparatively ‘old’ cars (currently 11 years old), I really don’t need the latest gimmicks, but compared to my first car (a BMW e30 from ‘89), it’s something completely different. I really enjoy the cornering lights, the climate control, the automatic BT connection to the phone and many other things.

If there is a problem with the home automation, I call in the specialist (if I am not one myself) just as I go to the workshop with the car. Sorry, but this is pure disparagement. That I get rid of the car when recurring problems occur is more understandable, but sensible home automation, compared to the complexity of a car, is fairly simple to maintain logic, wiring, and much less affected by external influences such as weather (for example, cable breaks happen to me rarely at home, contact problems due to corrosion are probably also significantly reduced).
How often do problems really happen with modern building technology, and wasn’t it perhaps due to insufficient expertise in planning and implementation (serious question)?

In a smart home, you can still switch lights manually and adjust the temperature, but with sensible automation, the proportion of times I do that will become negligible. We have now automated lighting, shading, and partly heating during the renovation. With a new build, I would definitely automate these trades again and even expand them (brightness sensors, dimmers, weather station, etc.) and wouldn’t skimp on integrating the front door either (the doorbell is not heard throughout the entire apartment and do I really have to walk all the way to the intercom to open it and hurry up for the guest’s sake to then wait in the stairwell until he has come up? Do I have to lock up separately, or does the house do that on its own, with all entrance doors when leaving?).
These are all things you can do by hand and (so far) do. But we used to unlock every door individually in the car, and no one would think of doing that today anymore. We are talking about basic, simple, and long-term tested automation tasks here, not about highly complex things like recognizing gestures to change the volume on the radio by circular movements of the index finger in the air.

I think for most people it’s still the fear of something ‘new and unknown’ rather than really rationally justifiable reasons.
