Just a coincidence that beer was discovered at roughly the same period...............

3000 years. I could believe it.

They call it the beginning of "collective intelligence". That's code for the distribution of responsibility away from individuals, or, idiocracy.

It's accelerating

What could ants teach us about human brain evolution?
Nothing.

Another hypothesis would be that agriculture and civilization allowed a larger number of smaller individuals to survive. Modern humans tend to increase in size if they have a better diet, especially in childhood.

“Ant and human societies are very different and have taken different routes in social evolution,” Traniello said.

Tranny is clearly a great genius.

3,000 years from now, AI computers will be studying how human brains started shrinking to the size of squirrel brains after the invention of the interweb and social media.

This theory could help explain why people living in large cities and sharing a common group-think are increasingly stupid. Their brains shrink because they rely on their mindless herd.

This appears to also occur with those who spend too long in higher education.

Those who are more spread out across the heartland and likely to be more self-reliant, perhaps growing their own food, fixing things, building sheds and other independent activities likely have larger brains.

“The externalization of knowledge in human societies, thus needing less energy to store a lot of information as individuals, may have favored a decrease in brain size.”

In other words, if people no longer need to be smart to survive, duller ones are more likely to survive to mate, and people are more likely to choose their mates based on other qualities, such as physical beauty, social status, and brute strength.

Imagine the brain size decreases currently evolving with generation after generation being supported by welfare benefits.

Is the far-left winning because they depend on their hive minds.
All decent individuals are smarter than any one parasite, but as a collective they win?

Someone realized sponging off of others was easier than innovation and hard work.

The premise of this hypothesis is very intriguing. If evolution is responding to the externalization of brain computation we should see even further reduction in brain size going forward. Once AI reaches the point of agency we may become so dependent on it to drive our cars, manage our economy, and even generate our movies and music that we will no longer need the analytical parts of the brain and will only retain the sensory experience centers.

We will live in a reality of sensual pleasure produced by our AI driven infrastructure and our biological brains will shrink to the size of walnuts supplemented by Borg-like connections to the “hive”.
