My NES hasn't received an "update" in the 37 years since it was manufactured, and it still runs fine. So does my Tandy 1000 PC. Didn't even have to replace any capacitors. This is what we want. Some time 15-20 years ago we started taking the wrong path with our tech.
I am old enough to remember appliances coming with full schematics printed inside their cases.
Electronics age out over time. The old stuff, made with more materials, take longer to age out. However, the old stuff does not have even a smidgen of the performance or power efficiency the modern stuff does.
Capacitors age because they are filled with liquid electrolyte, which dries out over time. Batteries age for mostly the same reason, and the chemical reaction slowly becomes irreversible. Those are easily replaceable. However, an integrated circuit is just a wafer of silicon. A piece of sand. It's going to take a long, long time for that to degrade. If it weren't for needing constant software updates and cloud connections to be useful, an iPhone could theoretically last a hundred years. "Tin whiskers" may also be a problem, but we are talking decades before you have to worry about that.
I don't think your theory about old things lasting longer because there is more mass to them is correct though. It really sounds like you are making that up because it sounds good in your head.
The larger components have more space between them... it takes longer for the "tin whiskers" to grow and become a problem. That and these old devices ran at higher voltages, so they have more tolerance to minor voltage fluctuations. Also, plastic does degrade eventually, copper traces can corrode, etc. Build quality matters, too.
Why do you need performance or power efficiency in a car's computer? It just needs to go when I press the pedal, and stop when I hit the brakes. That's not complicated, and something like battery wear leveling and temperature regulation can be a completely closed system and not require any updates whatsoever.
I really don't understand why cars need so much complex stuff, I just want it to get me from A to B, ideally in comfort. My current car that's >15 years old does that just fine with no internet connection, why do I need all the complex software?
Why performance...
Do you like your car's head unit to spend 1-5 seconds not doing anything before responding to your touchscreen or button press? No? Then yes, performance matters.
Power efficiency? Anything to extend battery life.
I don’t even want my car to have a touch screen!
Yeah, I don't need a touch screen. All I want is feature parity with my 15+ yo cars.
