I see nothing sad about that video at all - what is really sad is the comments within that video.
I also didn't think anything was "sad" about it...including the comments on it but I did think it was moving and made a very clear point.
But, as far as our opinions being different on this subject, I don't think that's surprising to either of us.
One of the other concerns I have is the potential effects of radiation from using electronic devices that are hands-on (cell phone; iPad etc.) with young children. This topic hasn't been fully studied yet and recent studies point to very real possible adverse effects.
As far as children becoming tech-savvy (regarding a comment from another poster)--I think if we wait until 2-years-old the kids will be just fine.
Everyone chooses their own boundaries with their children based on the information they have. I have chosen to wait until later to let my children have "screen time" and there is basis for this which is not just some draconian ban or decision based on a blanket statement.
Other people may be fine with their children having a constant entertainment, technology and stimulation flowing through various devices in and outside the home. I also love technology and am fond of my gadgets but...I also like solitude and sitting and listening without doing anything and I want my children to have a grasp on this--not be reaching for an iPad or iPhone at the first hint of boredom.
For us, we feel like our children already get more than enough stimulation (especially on the street in HK!) that we prefer to have the TV off most of the time and allow all of us some time to think without having to be stimulated--I think it might be a dying art, actually but for us I still think it's valuable.
While screen time may not actually HARM my children (in any obvious way) I don't always see the benefit. As a teacher, I teach children who often have a hard time focusing in a traditional classroom--largely due to being constantly over-stimulated everywhere else. So, until every school can have iPads for every student to interact with, I think there is value in teaching children that they don't always have to have a screen to entertain them.
So, yes, it is about balance but just because we have chosen a boundary doesn't mean we're not balanced or informed about our choice. I think my children benefit from this.
