But you can still buy some types of appliances without circuit boards (and with minimal complexity in general). When my fridge/freezer broke down, I bought one with a mechanical thermostat and no circuit board. Slightly higher power consumption and no display, but much cheaper and probably lasts longer. And since it has only high-voltage components, they are probably of higher quality thanks to certifications etc.
