Half the world’s population is still offline. Here’s why that matters.

Last month scientists at Tufts University announced that they had created a sensor that can be mounted on a tooth to track diet quality and make tailored nutritional recommendations.

Around the same time, Microsoft announced that it had developed software that could translate Chinese to English as fast and as accurately as a human. To top it off, just last week the world learned that there is now a robot that can autonomously assemble furniture.

Such stories make it clear: to read the science and technology news today is to see a world of rapid progress and infinite potential.

And from one perspective it is.

But we believe that now is a good time to remind everyone of a fundamental limitation of the ability of technology to make the world a better place. All of these advances in one way or another rely on the internet – a tool which remains foreign to over half of the world’s population.

The Broadband Commission for Sustainable Development says that the world will not even achieve 50% internet use until the end of this year. If the world maintains current internet user growth rates – a big if – we won’t approach 100% global internet adoption for well over two decades.

Internet of Things

In that time experts predict that the Fourth Industrial Revolution will be in full swing. We will be connected to a vast Internet of Things network that will feed unimaginable amounts of data into ever more advanced artificial intelligence tools, enabling us to create new and highly disruptive products and services that generate huge amounts of wealth. Or, at least those of us with an internet connection will be.

This looming and unequal wealth explosion is important because it will exacerbate the current fault lines of global inequality. Internet use is overwhelmingly concentrated in advanced economies, and the biggest gaps are in the world’s poorest areas.

This perspective, that countries with minimal internet penetration are likely to miss the Fourth Industrial Revolution, is why the digital divide matters so much now. It should play a much more central role in discussions about internet development at the global level.

The map and chart below shows hot spots of internet connectivity in most developed countries and huge opportunities to increase access to the internet in developing countries.

If this situation is not resolved soon the benefits of the Fourth Industrial Revolution will accrue principally to the global haves, leaving the have-nots even further behind.

This is not to argue that the only thing stopping one of today’s Least Developed Countries from becoming a global leader in artificial intelligence is getting their full population online. Rather, doing so would create a national digital ecosystem that increases a country’s chances of being a player. In particular we should not discount the prospect of emerging economies launching homegrown industries that offer tailored products to national or regional populations, driving economic growth and helping to fight global inequality.

Do not forget the example of M-Pesa, a leading global mobile payments provider that is 50% African owned and has its largest user base in Kenya.

This perspective, that countries with minimal internet penetration are likely to miss the Fourth Industrial Revolution, is why the digital divide matters so much now. It should play a much more central role in discussions about internet development at the global level.

To date, the argument in favour of prioritizing internet development has been tied to its potential to drive sustainable development. This is an easy case to make. Not only are there now many studies that show the macro-level growth benefits of increasing broadband penetration, but the stories of how the lives of individuals and communities are regularly transformed by the arrival of the internet continue to amaze. As internet development professionals we have seen these ourselves.

One of us saw first-hand how a poor Indonesian entrepreneur grew his income seven-fold in nine months when he received an internet connection in his home. He used Facebook to find distributors for the food product he made, convinced several to make a visit, and signed contracts with every one.

The other witnessed how an eight-year-old boy was able to use the internet to save the local economy of a village in northern Brazil. The village survived on selling chickens, and a very large number of local hens had recently begun eating their own eggs. This was traditionally seen as a sign that the bird was possessed by spirits and needed to be put to death. But the boy was able to find a YouTube video that explained it simply indicated a calcium deficiency in the chicken’s diets, well within the villagers capacity to solve.

Yet as compelling as these arguments are, they have not adequately swayed the global debate.

Despite the fact that the rate of internet growth is too slow, despite the fact that the Global Infrastructure Hub has identified a $1 trillion global financing gap for Information and Communications Technology (ICT) infrastructure between now and 2040, over the last six years multilateral development banks have devoted just 1% of their resources to this issue.

Why? A recent survey supported by the World Wide Web Foundation showed that investment in ICT connectivity is seen overwhelmingly as the domain of the private sector, and specifically of mobile operators.
