Wikipedia. Google Maps. The store of knowledge available from search engines. I use those all the time. You want to cut them off from that?

That’s a bit overdramatic. Most kids have a laptop for schoolwork these days. I personally didn’t get a smartphone until I started university, got a Samsung S7 then. I had no issues accessing any of those sources. These days I have a comp sci masters degree, so it definitely didn’t “stunt” me in any way.

I read and certainly write way more text than I did in the pre-Internet era. Do you want kids reading and writing less?

Kids reading and writing skills appear to have been declining ever since the rise of the smartphone, so I doubt they’re reading anything of sufficient quality to hone those skills a bit.

Schools here have recently mostly banned smartphones, and the kids seem happier for it and their grades and concentration in school is improving. Sound like positives to me.
