First time I've heard that but certainly makes sense.

The brain is designed for information storage as well as other functions.
Do not use the brain you could lose it. How many people can compute a math problem using just their brain? How many can memorize a map by looking at it just a couple times.
How many people rely on travel GPS in their car to get where they are going?
How many phone numbers can you memorize of people you know? I still know my parents home phone number from 70 years ago.

Very cool, glad I'm an old fashioned boomer, alcohol destroyed my brain.

Electronic devices have dumbed down people. You have high school kids that can't write in cursive because everything is typed on a computer, everyone uses calculators for the simplest arithmetic, people use GPS instead of reading road maps, people can't make change because everyone uses a debit card, people bookmark info instead of memorizing it...

And here I thought it stood for "Alotta Intoxication"
