1. How much creativity was blossoming in the 50s-90s from your average man-or-woman on the street who wouldn't own a smartphone? Not all that much. Maybe a few slightly novel yet cliche jokes a week, if they were particularly sharp.
2. Not very different except for the fact that there wouldn't be groups trying to make smartphones into their favored scapegoat for society not going exactly how they wanted.
3. Not any more likely than that keeping teens out of dance or pool halls would keep them devout and in church 'and on the right path'. Procrastination is an emotional regulation mechanism and emerges as a natural consequence of activities conditioning yourself against wanting to engage in them. Sometimes it is your mind saying "I don't want to do this right now." Other times it is is "I literally cannot do this right now!".
