> Neuroplasticity is the brain’s remarkable ability to adapt its structure and function by rewiring neural connections in response to learning, experience, or injury.

The invention and innovation of language, agriculture, writing, and mathematics has driven the change in neuroplasticity remodeling, but the overall structure of the brain hasn't changed.

Often in modern societal structures there has been pruning of intellectuals, i.e. the intelligent members of a society are removed from the gene pool, sent to Siberia. However, that doesn't stop the progeneration of humans capable of immense intelligence with training and development, it only removes the culture being passed down.

And, I say, with strong emphasis, not only has the brain of humans been similar for 25,000 years, the potential for sharpening our abilities in abstract reasoning, memory, symbolic thought, and executive control is *equal* across all sexes and races in humans today. Defending that statement is a hill I'm willing to die on.

"Mindset" by Carol Dweck is a good read.

You are just looking at the wrong people to compare.

Leonardo Da Vinci would be a PhD student working on some obscure sub-sub-sub field of something and only 6 other people on the world understanding how marvelously genius he is. The reason they don't get to such a status is that human knowledge is like a circle. A single person can work on the circumference of this circle, but they are limited by what they can learn of this circle. As society improved, we have expanded the radius of the circle greatly, and now an expert can only be an expert in a tiny tiny blob on the circumference, while Leonardo could "see" a good chunk of the whole circle.

"Thought leader and inventor" are VC terms of no substance and are 100% not who I would consider smart people on average. Luck is a much more common attribute among them.

I mean, how docker works (which is mostly a human construct with its own peculiarities) is not what I would use as an example - this is more like a board game that has its own rules and you just learnt them. Ancient people had their own "games" with rulesets. It's not a "fundamental truth".

Societal smartness might be something like an average student knowing that we are made from cells, some germ theory over bodily fluid inbalances causing diseases, etc, very crude understanding of more elements of physics (electronics). Though unfortunately intellectualism is on a fall, and people come out dumber and dumber from schools all over the world.
