Your Brain Is Not a Closet

Artificial memory (such as what we can draw upon from databases) is not the same as natural memory (from our brains). As David Brooks writes in his op-ed piece "The Outsourced Brain", artificial memory means we can follow prompts from a GPS-enabled computer in order to drive ourselves home. That drive may be easier, faster and less stressful than it would otherwise and we certainly don't need to understand the road system to arrive home.

However, too much reliance on artificial memory has its shortcomings. I think one of the biggest areas is developmental shortfall and atrophy of mental skills.

For example, while using a calculator speeds up a lengthy calculation and makes it more accurate, should we always rely on a calculator even if it is accessible? I have seen people use calculators for tasks that take more time than mentally multiplying numbers (I used to have a boss who would use a calculator to multiply by 10).

Using artificial memory whenever possible can lead to mental laziness. The brain doesn't seem to be like a closet with a limited capacity that can be used to store one memory at the expense of another. Instead, use of our memories should enable us to uncover patterns and insight that would not come out merely from use of artificial memory.
