I wish there was a somewhat rigorous way to quantify reliability of tech products so that we could conclude if tech on average was about as buggy in the past.
I mean I also feel that things are more buggy and unreliable, but I don't know if there's any good way to measure it.
Flash forward to today. I can't remember the last time I replaced an ignition system component. I still don't know how they work. I can guarantee that the techs who do occasionally replace them at the dealer don't know how they work. But the whole system is so much more reliable.
That said, I do wonder how young people are supposed to learn and gain understanding in a world where they cannot possibly understand the components in complex systems. Back in the day (I know, yelling at a cloud), I could actually understand how a set of points and a distributor -- or a even a three-transistor radio -- worked.
