I think so. Also half of the people don't have children and/or have a lot of free time. I am not even talking about responding to emails/family chat.

How do they do 2-factor auth to Heroku/Gitlab/whatever? Maps in a foreign country where you can't even read the letters? On way to job interview when the interviewer has an emergency and needs to postpone? Good friend is in the town and calls you to hang out? Translation when a tourist comes to ask where something is?

I get the general point, especially as IRL payment options are also increasingly assuming you have a smartphone, however maps and translation can also be done offline.

Hah, I hadn't even thought of banking/payments on the go. And true regarding the offline maps - a few sister comments mentioned leaving phone at home though.
