Could Google, the world’s largest search engine, be causing our memory banks to atrophy? Maybe, say four Columbia University researchers, who believe Google’s instant-retrieval search mechanics could be training our brains to jettison information we’re sure of quickly finding again with a few taps on a keyboard.
“The Internet has become a primary form of external or transactive memory, where information is stored collectively outside ourselves.” Retrieving a memory has become as simple as reaching into your pocket for your cellphone. Pocket Brain.
Long term reliance on this source may produce a condition similar to Alzheimer's disease. As symptoms worsen over time, the disease will progress through 3 stages. In the early stage, you may notice some mild memory loss, but, as the disease progresses to the moderate and severe stages, you may notice new symptoms appear or existing ones worsen.
When it has progressed to the severe stage, humans may lose the ability to perform daily activities, like carrying on a conversation or even being aware of their surroundings.
Scientists predict that as the human brain continues to atrophy with reliance on personal devices for memory retrieval, and from the lack of social interaction..... head sizes will shrink by one-half by the year 2070.
