I still do use an alarm clock. I don't like a radio transmitter close to my head for several hours while I'm sleeping. Nor I make love with my phone, so it's useless in the bedroom. It stays charging in the studio.
Nor all people can use a monitor everywhere with a PC attached - even if it's a Raspberry, a Chromecast or a Firestick. At least a plain, small TV doesn't send "telemetry" out (yet).
