A few issues here. Firstly, it is a genuine battle that parents have to wage against the prevailing norms. My daughter sees all her peers glued to their screens and I have to constantly remind her to "look at the zombie retards" just to balance the propaganda.
To her credit, she actually seems to use her screen time to learn stuff. One unexpected result is that she is becoming a very good stage actress and can learn her lines with relative ease.
So such devices, such as tablets, can be useful but I still monitor the zombie-creep and delete any shit - which is rare as she knows I will delete it!
But this is all similar to many other dumbing down techniques such as the toxification of our whole environment. Again, I'm teaching her how to read ingredient labels and also important is for her to experience the difference.
I child who would normally have a healthy wholesome diet will, when pointed out, actually experience the distorted behaviour from junk food, sugar overdoses, aspartame, msg etc etc. Many kids are so seriously screwed that they prefer synthetic flavours to the real thing, to the point that the real thing no longer has that buzz. To the point they don't even perceive the harm coz their drug-dealing doctors will point the finger at the wrong cause.
One last point about electronic devices is that they are physically harmful. The EMF is damaging to all humans - the research is either suppressed or defunded or ignored. And yet, the biophysics shows us that EMF can interact with the brain and yet the propaganda will claim it doesn't. 100% evil lies. The published research goes back to the days of radar in the 1950s, so it is there, if one cares to look.
But as the zombies are too retarded to notice, they become a large part of the problem. I am less than optimistic. I checked and 5G will be rolled out experimentally here, in a business zone, but avoiding Bangkok... for now.
