Technology is not always a good thing.
One example is with the children.
In the old days, children used to play outside with their friends.
Now majority of them are just staring at their iPads.
Per my daughter's pedia, children below 2 should not use gadgets because it may cause speech delays. For children older than 2 i think it's ok to use gadgets as long as there is time limit like 3 hours per day so that they can still do other things they supposed to be doing like playing with their friends or just have conversation with family
