Sure, but you're not designing interfaces and technology for those that aren't online, are you? Like, you're not making an app for rural Pakistanis that can't read and don't have smartphones.
The whole world might be online at some point, but you'll still not design your apps for Pakistan, because the difference in adoption speed of technologies, trends, cultures etc will not go away just because they are technically online now.
That's not to say that Pakistan itself won't be a strong market to target. But It's a niche market, you'll likely not target the US, Pakistan, and France in one app, just like you don't today.
