I disagree a little bit with you.  One clock radio I pulled apart had a mechanical time display and while the radio was indeed an inscrutable PCB covered in components it matched the level of complexity I expected to see.<p>Nowadays the complexity is hidden under a smooth patch of black plastic that can have smart phone levels of complexity internally and no hint at the that from the outside.<p>Obviously it&#x27;s swings and roundabouts since you can indeed find a wealth of information online about any of these subjects but sometimes it feels like it&#x27;s harder to kindle the initial fire of curiosity.
