I am of an opinion that we give too much to our brain helpers: you can get everything from the Internet, so you don't need good memory or internal knowledge; you can get direction from the Maps app, so you don't use your sense of direction, etc, etc.
Soon, we would be kind of dumb people surrounded by gizmos, then we would probably lose our "toys" and be just dumb people, but then, over 10000 years we might become "smart" again.
An original "Dune" scenario.
Sounds as much like an "Idiocracy" scenario.
Your knowledge is a precious thing. Use it or lose it.
Yeah, but in "Dune" people fought gizmos, which is one possiblepath so far, I would think...
...in "Idiocarcy", people grew "dumb" because, according to the movie, "dumb" people had more children as a primary cause.
This might happen too plus, we have decreasing fertility, T levels, etc, etc.
