Same in the US when you zoom out.

There are studies about how other tools reduced various capacities. Our memory capacity has decreased and how we use it has changed. People used to store a lot of information, now we only store a sort of index (we remember where to look it up, not the information itself). Our attention span has also greatly decreased with the shift to short form content (not a useful tool, but just another cognitive change).

That part of the story was heavily hollywoodized. I highly recommend reading the original story.
