6) Internet’s future

The internet will be a thriving, low-cost network of billions of devices by 2020, says a major survey of leading technology thinkers.

Current estimates indicate that one-sixth of the world’s population is now online. Given this level of growth, it is not beyond reality that we may see over three billion people online by 2010 - that’s nearly half of the world’s population!

This anticipated growth can be attributed to two main factors - mobile technology and the increased localisation of content. Louis Nauges, president of Microcost, a French information technology firm, saw mobile devices at the forefront of the net. “Mobile internet will be dominant,” he explained. “By 2020, most mobile networks will provide one-gigabit-per-second-minimum speed, anywhere, anytime. Dominant access tools will be mobile, with powerful infrastructure characteristics. All applications will come from the net.” But not everyone felt a “networked nirvana” would be possible by 2020.

By 2020 an increasing number of people will be living and working within “virtual worlds” being more productive online than offline.
