Ok, I actually kind of do know how "that child would turn out if they didnt have the gadget"
Dd and ds1 did not have gadgets at age 8. Actually they had a very old ps1 and a few games. They are now 15 and 14
Ds2 had, at 8 an iPod touch, a third share in an iPad and a DS.
No difference at all.
They all had the same level of concentration, the same imagination, the same ability to play on their own, all liked drawing, singing, bike riding, sports.
I honestly think that of course if an 8 year old has no interest in tech, then fair enough. But the world moves on.
Back when I was a teenager we didnt have Internet access, mobile phones, social networking, texting, bloody Instagram. But things develop and there's no point pretending otherwise and feeling superior because you do not allow your child to use it.
My DCs use the Internet for 90% of their homework.
I don't tell them they can't do that because it is commonplace and as they get older and go out to work they are going to need to use done form of tech at some point.
There are no brownie points for not allowing your DC to use this stuff. No, of course you are not holding them back by not having an iPad at 6.
But the reality is, the world is much more centered around technology now and that is not going to change.
