Minecraft is absolutely not helping in the war on screens. As a former educator I laugh heartily at the proposition. Although, I did use "screen time" as a gift-able and earn-able commodity, and in a small classroom of kids it works great to encourage sharing, participation, group watch / observance, and "can I please share with Timmy now so I can have more screentime later?" [success fist]
So, is it like the war on drug and war on terrorism ?
Also I remember when I was a kid, people were over my back for reading too much books, as I was supposed to “go outside”, “play with the other kids”, “make things with my hand”. I won’t use the eternal ‘I ended up fine’ argument, but in any day and age we’re grindingly pushing kids toward stuff they don’t care about for no decent reason. As a general rule you shouldn’t be at war against stuff your kids are into.
