None of that disproves his point. Google Talk could have been WhatsApp, very easily. They were in a position to make it happen before WhatsApp had even started development - Google Talk had enjoyed a meteoric rise and dominance over the messaging market for 4 years before WhatsApp came out, and it took WhatsApp quite a bit of time past 2009 to gain the steam it did.

The fact that they failed to capitalize on it is what has allowed WhatsApp and others to become as big as they have. If Google hadn't messed it up, everyone would be using Google Talk, even in the 3rd world.

You live in a bubble, but your bubble is different from their bubble. Thank you for being kind enough to share what you leaned growing up. It helps us all see past our own bubbles.

I am from a rural part of India and everybody has a Jio phone and everybody is on WhatsApp and Facebook. Most of them don't even know what is email and I don't know anyone who uses email or any other chat service other maybe Hike in rare cases. I was surprised since they already have Facebook and it would have required an email.

I often get disapproving looks when they realise I am not on Facebook :)

I think you really need to check how people use Internet in India, Indonesia and other Asian/African countries. I doubt anyone uses laptop or desktop PC unless it's needed for work. And Internet cafe is a thing of the past.

Having wifi but no cellular signal is such a rare usecase.

I'm from China where WeChat dominates everything and SMS are nothing but to receive verification codes. Almost everyone here use WeChat as their contact and Contacts.app is merely opened no more than once a month. This phenomenon is common from giant cities, like Beijing and Shanghai, which are at least as developed as NYC or SF, to small cities in the rest part of the vast country, which are absolutely 3rd or even 4th world.

I agree with your point that in some countries people don't use Email and that's the face in China as well. But people use phone numbers just for register other services, as the online identity. We don't use SMS, and we prefer WeChat Audio over phone calls when it's available.

But those things don't sell here. Maybe businesses and professionals buy it but not regular folk. All of them are buying smartphones in millions and going online everyday. Cellular signal is the norm all over the country and we have around 80% of it as villages. So I'm pretty sure all of those use cases come at a distant second. Please read about the impact of Jio in India.

Please understand that the size of the population which uses this limited use case in my country is greater than multiple western countries' populations combined. I've been a developer for nearly 7 years and make a good amount of money in my country. Yet I've never touched an airplane. I'm telling this to point out the difference in living styles between the two zones of earth. All tech companies are rushing to capture market in the developing countries because we are poor now but in 20 years we may well be up there along with you all.
