The claims are made for improving stone technologies co-related with evolutionary changes in brain structure. Why not with modern technologies ?
It could, provided brain structure better suited to modern technology is both heritable, and has a positive impact on the bearer's reproductive success.
But in a extensively interbreeding population, such changes don't lead to speciation. It merely leads to changes in the overall gene pool over time.
