Macquarie University studies man vs Wi-Fi

A paper by Macquarie University and US researchers has highlighted the importance of understanding the internet as an organism that can evolve, opening up a can of widgets when it comes to the implications for life on our planet.

“Life on Earth is driven by the information encoded in DNA, and there are around 530 billion, billion, billion, billion nucleotides—the individual components that make up DNA—on the planet, which is a huge amount of information. However, the amount of information on the internet is predicted to exceed even this huge number in about a hundred years,” lead author Professor Michael Gillings explained.
The main advances in the complexity of life, the authors argue, can be explained by improvements in the way information is stored and used by life forms. For example, early life forms on Earth replaced less stable molecules with the stable and well-known DNA molecules that we see today. This simple replacement allowed the organisms with DNA to pass on information with greater ease and grow reliably, which led to organisms being able to consist of more than one cell, evolve a nervous system, and eventually become complex beings such as humans, with intricate societies and languages. Akin to this process, each year the internet grows in size by 30 to 40 per cent and is accompanied by new ways of sharing and using this digital information. Simply put, the digital world is evolving, and is likely doing so at a much faster rate than that of the biological world.
“What we’ve seen throughout the history of our planet is that evolutionary advances often result in the extinction of earlier species, which means we should be working towards avoiding this fate when it comes to technology.  Already, artificial intelligence can beat us in chess and on game shows; we rely on it for stock market trades, for operating trains and planes, and for maintaining our power grids,” Professor Gillings said.
The problem, the authors say, is the fact that we are already relying on the digital world too much, including being directly linked to it via handheld devices, and even medical implants. These technologies will soon allow direct brain-to-internet communication, potentially leaving our own minds open to attack by a digital organism.
“In biological terms, fusions like these between two unrelated ‘organisms’ are called symbioses. And in nature all symbioses have the potential to turn into a parasitic relationship, where one organism fares much better than the other. We need to start thinking about the internet as an organism that can evolve. Whether it cooperates or competes with us is cause for considerable concern,” Professor Gillings concluded.
