Internet Limited?

With more and more people using it every day, and colossal volumes of information being transferred every hour, the internet is growing fast, but how long can it continue to grow? There are limits to the speed and volume of data transfer that can be achieved, and when they are hit, it could well cause a huge depression in the internet, which could in turn cause what are now massive companies to fall, simply because they rely entirely on the internet to do business. Some experts estimate that the internet will only be able to cope with this level of growth for a few more years, at which point there will be periodic shortages, and a lot of the work since the .com bubble burst will be rendered worthless.
