    I understand smartphones. They are relatively simple devices.

    Apart from GPS and 5G communications which are pure black magic.

    And magnets: magic

      Simple…? Just understanding how transistors can be combined to generate a picture on a screen is crazy complex.

      Magnetic fields are a big part of smartphones in various, different uses. GPS is low tech compared to how the CPU is made.
