My pet peeve?
Everybody's complaining how "nowadays" electronics last shorter than ever, but it's been the same song for decades and decades, as long as I can remember.
Obviously this is just impossible, given limitations of physical reality, such as product lifetime having to be a positive number. It's the same story how certain people can't stand how Christmas advertising "starts earlier every year", have complained about this for decades. What, does it start in January now?
If you look at the advertisements from 1950's, consumer electronics was always about price. It always was race to the bottom.
Really the only actual reason why people erroneously think that old electronics was more reliable, is the selection bias, those products, or very simple products, that somehow ended up lasting long are here to stay. All crap was thrown away after fixing them become non-option.
I do accept the argument that relying on software ecosystem on the cloud makes "bricking" otherwise functional devices a real possibility and this has actually happened. But this is not what people complain about, they complain about build quality and component quality, which in reality is better than ever. 1960's television sets required constant servicing, it was completely normal to have repairmen come over and replace components, fix solder joints etc, and people were relieved when they could upgrade to a newer gadget, for example color television.
Someone somewhere said well that today's commercial grade components are equivalent to the military grade of two decades past and this is easy to believe. A $0.005 part of today includes more qualifications, data points and design guidance than a $100 military part of 1970's. While failures do still happen, the sheer number of electronic gadgets in an average household has skyrocketed. This is all enabled by the fact that devices are surprisingly long-lasting. Heck, I can't remember when I last time had a failed electronic device. Oh, I had a capacitor failure in an ATX PSU 15 years ago. Capacitor problems were common back then. This problem has nearly been solved as well.
