What would you change about modern society?

I’d start by putting timers in smartphones. The kind that automatically locks you out after 4 hours on it. You’d spend those 4 hours more wisely I’m sure.

Make all boarding passes electronic & for the smartphone. Paper is wasteful & it’s easy to lose it.

That all carrying on bags would come with a scale so you know when you’re over the limit & have to check it. So no surprises at the airport.

That more airlines would board by groups instead of by rows. That all airlines check carry on bags before they reach the gate.

That you’d get a notification if you actual mail in your mailbox instead of having to guess.

That smartphones would be used in a limited capacity & not for everything.
