人間の脳の一部に、前頭葉というものがある。
A part of the human brain is called the frontal lobe.
。
It is believed that the frontal lobe is responsible for controlling motivation and emotions, as well as switching between thinking and imagination.
。
Furthermore, it also plays a role in the retention of long-term memory.
。
However, it is said that this is the part of the brain where aging begins the earliest.
。
There are concerns that it may accelerate the aging of the frontal lobe.
。
That is digital technology.
。
As people become increasingly dependent on computers, smartphones, and the internet, opportunities to store information and knowledge in their own minds or to recall them frequently are decreasing.
。
There is also an opinion that this further accelerates the aging of the frontal lobe.
。
According to an increasing number of opinions, the vast amount of information accumulated in the digital world can be regarded as a newly given external brain for humanity, and it is said that this helps to improve human efficiency.
。
Many experts believe that if we had an external brain, we could fully utilize our own brains as places for thinking, rather than just as storage devices for memory.
。
However, if the cost of relying on external brains is to accelerate the aging of the frontal lobe, we need to approach this view with caution.
。
You can only form associations and make judgments after information and knowledge are stored in your own brain and put to use.
。
外部脳ができたことを謳歌する前に、自分の脳を鍛え、活用することの重要性を再認識する必要がありそうだ。
闇雲にデジタルへ脳の役目を託すことは、危険を伴うと言わざるを得ない。
外部脳に人間の脳が持つ元来の力を奪われかねないのだから。
