Often people’s wake cycles are triggered by light. You can actually buy an alarm clock which uses gradually brighter light to softly awaken you rather than music or alarm. And then of course there is the rooster.

As a kid I would wake up without fail at 7:30 am for school without needing to set the alarm. Maybe if you took away all the alarm clocks in the world people would adapt and wake and get up on time anyway.
