A lot of people are genuinely stranded if their phone runs out of battery. How do they pull up a map, or call an Uber, or phone someone to pick them up?

I'm not sure the point you're trying to make. This was true before cell phones too. People didn't carry maps everywhere.

What's the difference between then and now?

Pay phones, basically? Physical maps being available in public places more readily?

The argument here is "most people can get by just fine" without access to the internet.

I tried to pick an obvious example to illustrate how that's not true.

The difference is that, prior to everyone having a smart phone, people had backups for if they ran into trouble. They might simply not go somewhere that they might have trouble returning from. They sorted out their travel plans in advance - someone to pick them up from a location at a time. They memorized phone numbers so they could call from a pay phone if they needed to. They carried cash or a cheque book to pay for cabs.

Fair enough. I suppose a better argument would be "people can learn to get by just fine without the internet if they have to"

But you're definitely right. We become pretty reliant pretty quickly. I think that should be concerning with the way technology is trending in society

The cellular phone network doesn’t require the internet to work.

It does require the phone to have battery charge.

The context was “Everyone does use the internet for everything today” and “most people don't even realize how the internet is running literally everything”. You don’t need the internet for your phone to have a battery charge.

They were providing some illustrative examples: most people rely on the internet for maps. If they don't have internet (because their battery is flat) they can't do xyz.

I was referring to the claim that they couldn't phone someone to pick them up.
