They're not being raised without tech at all, they just don't have their own devices, or any open access to one.
Their screen time is limited to a small amount of passive consumption per week (2 * 1/2hr episodes on Netflix per week, or a movie), and engaged or creative use of a tablet for about 2h/week. Lately that's been drawing tutorials on youtube, duolingo, wordle.
We're pushing off allowing them to have their own phones for as long as possible. We're friends with a lot of families with the same approach, but also a lot of friends of my older (10yo) kid do have phones already. At some point it will be very difficult when they start getting left out of the party (so to speak).
My best case scenario is that the extra time this frees up will give them the space in their lives to grow talents and health that they wouldn't otherwise. I'm much happier to see my sons getting really good at pencil drawing and playing soccer than having a social media profile or being good at some video game. I feel having a really healthy body and some old school analogue skills like drawing will carry them further than whatever general digital distractions have to offer.
