> I speculate--don't allow them screen time.

This I take as a given as a very positive parental attitude. Children have to much screen time, reduce if possible.

It's this myth -

>It's a comfort and familiarity with the computer that allows the user to easily adapt to new things.

That worries me.

Too much computer time is devastating to the brain and the person.

Less is way better than to much.

Of course the just right amount is best. But since 50% of parents are below average parents, I think encouraging less is better than more. Screen time is swamping children, it doesn't need to be encouraged, the myth of the first world kid not getting enough computers is like the myth of the first world kid not getting enough calories.
