Is the Internet Shrinking Your Brain?

I wonder what evolutionary changes will be caused by our growing connection to the internets.
In Kensy Cooperrider's podcast episode “Why did our brains shrink 3000 years ago?” — Many Minds, Feb 2, 2022 - he spoke with guest Jeremy DeSilva from Dartmouth. The episode discusses the late, post-growth shrinkage of ~“a lemon’s” worth of brain volume, and explores possible explanations. (Hold a lemon beside your skull. That's a lot of volume.)

A brain is both incredibly useful and very expensive. Brain cells use more calories than other cells. And the larger the brain, the higher the risk that birth will kill the mother or child. So if it were possible to get by with smaller brains, evolutionary pressures would choose that direction.

DeSilva says there are various theories about why the brain shrunk just 3,000 years ago. One is that society had evolved to the point that one could outsource collective cognition. For me an even more interesting possibility - and in a way related - is that this brain shrinkage coincided with the emergence of reading and writing. One didn't have to hold as much in her head if she could hold it instead in her library.

How will our growing ease of connecting with so much data, so many people, and so many virtual experiences online change our brains? Could it shrink them even further?
