Just how did it happen? More than half the earths population doesn't own a credit/debit card, most stores in most countries don't accept them either as they don't have a terminal.
Who in hell uses video calls? i mean seriously, i have not seen anyone use that function in any county i've been to for the past 5 years.
The third one is debatable, depends on how you percieve handheld gaming. I would actually agree that cell gaming destroys regular handheld gaming.
Third world and other eastern countries don't count. We're talking about civilized human societies who are able to function a TV, etc.
In these countries cash is no longer used (or at least hardly) and everyone uses video confrencing. I haven't seen anyone use telephones in over a year. It's very rare now.
