We've raised both our kids with "no-screens" (now 5 and 9 yrs old). They don't have their own devices and may not use ours. An exception is for the 9 yr old to use the laptop when learning to code at scratch.mit.edu. If they need to watch something - its a movie on the big screen in the evening only on if the next day is a school holiday.
Yes - they turn almost anything into a toy. They have access to all sorts of stuff to build things - lego, clay (and clay sculpting tools), scissors and paper, plenty of board games, and outdoors even when cold and/or rainy.
