The "When phones had wires, humans were free" idea ignores that back in the day when the phone rang, you'd stop whatever you were doing and answer it. There was no Caller ID, no voice mail. You picked up the phone not knowing if this was an important work call, a social call from a friend or relative, or somebody trying to sell you something. Yes, a mobile phone means you can be contacted anywhere, but on the flip side you are free to ignore it, safe in knowing that you'll miss nothing of importance. People will leave a message, or at least you can see who called.
