I don't know, it's different. Humans are analog wonders, phones are digital wonders, both impressive in one of those categories.
Likewise, phones have numerous analog components: microphone, speaker, camera, screen, radio modem, power regulation.
Please don't equate the word "digital" to the notions of being electronic, man-made, or modern. Digital is simply an agreement between a sender and receiver that information is finite and perfectly copyable. (By contrast, analog information is infinite and cannot be copied perfectly.)
