Many people in first world countries will. Some people in first world countries and probably most in Indian villages don't even have 4g yet. So I doubt that in 1000 days they will have 5g when we are barely producing any devices today with that capability.

The reason they don't have 4g now is mostly because there's no 4g service, not because people can't afford 4g enabled phones. I'm pretty sure by now 4g phones are just as cheap as 3g phones.

New phones, yes. But many people don't have new phones. Especially in poorer places.

1000 days if substantially shorter than the lifecycle of phone models. New cheap phones today don't have 5g, you see the timing issue?

How do they access internet right now? Whatever that is, it will continue to be available. Those who want something better will upgrade their phones.

Not so soon and definitely not in India.

The same could be said about having fiber to every village, yet here we are discussing just that.
