Planned obsolescence is technically difficult: it’s relatively easy to design and use a material which lasts indefinitely, but harder to design a machine around materials that last a specified period and then fail. You need to tread the tight-rope between “too shitty to buy” and “too high quality to require frequent replacement.”
Some say that it failure comes with miniaturization too. Those SMD capacitors fail a lot easier in electronics, so while the microwave might still work, the display will fail pretty quickly.
