Dr. David Geary, an evolutionary biologist, has raised concerns that the increasing reliance on artificial intelligence (AI) could lead to a shrinkage of human brains. Geary argues that as AI takes over more cognitive tasks, humans may lose the need to develop and maintain certain cognitive abilities.
This, in turn, could lead to a reduction in the size of the human brain over time, as unused areas of the brain atrophy. Geary points to the example of the human appendix, which has shrunk over time as humans have adapted to a diet that no longer requires its function.
Geary's warning highlights the potential long-term consequences of relying heavily on AI and automation. While AI has the potential to greatly improve human life, it's essential to consider the potential risks and ensure that humans continue to develop and maintain their cognitive abilities.
