1997, 2007, and 2017 in the classroom

So this Reddit post is likely a little old (I guess I'm a little late to the game here) but I saw this and thought it was pretty accurate:

I can't say I've ever had a problem with texting (or Netflix) IN class (mostly because of good cell phone policies where they are supposed to stay in student lockers)... however sometimes my students have taken exceedingly long bathroom breaks and you've got to wonder... did they really need to use the facilities or did they need to play another round of Fort Nite?

But what else is different?

I racked my brain but couldn't think of anything.
